John mexico city, one of the worlds most populous cities, could be just months away from running out of water. Its been brought on by a combination of geography, mushrooming growth and leaky infrastructure, all compounded by the effects of Climate Change. Emily green is a journalist based in mexico city whos covered this story for npr. Emily, whats the situation there now . Whats daily life like now for just for you. You live there in mexico city or are there restrictions on water use . Emily there are restrictions on water use. I think it very much depends where you live in the city. And that is maybe like the entire world, you know, if you have more money and youre going to feel the impact of the water shortage, much less. That said, i think whats unique rit now is that it is being felt citywide, and ill just use myself as an example. I live in one of the more upscale neighborhoods of mexico city, and while reporting this story, the water stopped flowing from the tap. I mean, i had a sink full of dishes, zero water coming. For me, it was a little shocking. I havent had that happen in a while. But that is actually a daily reality for many people in mexico city. John what are the factors that brought us to this point . Emily i would say that there is two major factors. One is extremely old infrastructure in terms of the water pipes. So the city loses around 40 of the water it receives because of leaks in the pipes. And thats been a long standing problem. But on top of that, compounding that, is Climate Change. And that is really whats happening right here. You have this very, volatile combination of old infrastructure cbined with Climate Change, which means there have been years of much less rainfall than normal, so the levels of the reservoir that provide the water to mexico ci, theyre theyre very low. And so thats whats happening now, this kind of volatile combination. John and you sayeakage has been a problem for a long time. Has anyone tried to do anything about it . Emily oh, yeah. I remember i was here in 2018 and the city shut off the water supply in order to try and address these leaks. That was one of the first water stories i did in mexico city was at that time. But of course, were still having the same issues, so it doesnt seem to have made a huge difference. John and you said earlier that that people who are better off feel it less than maybe people who need you may be in need. Is that because of the resources they have, or is it the parts of the city that were affected . Emily both. I visited one area. Its called ecatepec. It is in the greater metropolitan mexico city and in this neighborhood, they havent had Running Water for two years now. And the Running Water that they do have, it comes out and it looks dark brown and it smelled like sewage. So that is an example of where they are living in the city has a major impact. But i think on top of that, whats happening is that if the water is not coming from the tap, people are buying it from private water tanks. They are having it trucked in on water tanks. And its just a fact that that 70 that one spends is going to impact you more or less, depending on how much money you have. So its that combination of where you live and also how much money you can afford to spend on trucks, private trucks, bringing in water and paying for that. John what are the potential effects on schools, hospitals, homes . What are the people worrying about . Emily if you dont have water, you cant flush the toilet, you cant do the dishes, you cant wash clothes. The list goes on and on. And so it does have a massive impact. The former chief resilience officer of mexico city, said thatlimate change is really the greatest risk to mexico city. And i think that that is coming to bear right now. John and if Climate Change is the greatest risk, it sounds like, is there anything anyone can do about this right now . Emily yeah, you can use less water. And i think that there can be measures taken to ensure that individuals use less water, but also factories use less water. I think also this issue of the old infrastructure is a really serious one. And i think that steps can be taken, to improve the, the infrastructure. So i would say its again, its theres no Silver Bullet to whats going on right now. The causes are very varied and the solutions are also going to be varied. John has anyone said that if nothing changes, have they predicted when taps are just going to run dry in mexico city . Emily i mean, thats the talk of the town here. Its what they call day zero and this is the idea that the taps are essentially going to go run completely dry. The date thats being thrown out there is at the end of june. Most of the experts that i talked to say thats unlikely to happen. The reservoirs that supply a great percentage of mexico citys water theyre not the only source of water. Theres also underground aquifers. So its unlikely that the city is going to completely run out of water, but this is a very, very, very serious crisis. And it is not as if we know that next year theres going to be a huge amount of rainfall, so if this drought continues, i dont even want to imagine where were going to be in a year or two or three. John emily green in mexico city, where theyre running out of water. Thank you very much. Emily thank you. John shakespeare may have said that music be the food of love, but increasingly these days, the language of this very real emotion may be artificial intelligence. Ali rogin tells us about this growing phenomenon in the search for companionship. Ali for some users, they are a friend to talk to. For others, and for a fee, they will even become your boyfriend or girlfriend. Computerized companions, generatecompletely by artificial intelligence, are becoming more common. And the bots are sophisticated enough to learn from prior conversations, mimic human language, flirt, and build personal connections. But the rise in ai companionship also raises ethical concerns, and questions about the role these apps can play in an increasingly disconnected and online world. Haleluya hadero covers technology and internet culture for the associated press. Thank you so much for joining us. Tell us about these ai companions. How do they work and what sort of services do they provide . Haleluya like any app, you can download them on your phone and once its on your phone, you can start to have initial conversations with a lot of the characters that are offered on these apps. Some apps let you do it for free. Some apps you have to pay subscriptions. For the ones that let you do it for free, there are teirs of access that you can have so you can pay extra, a subscription for unlimited chats for, different statuses and relationships or replika, for example, which is, you know, the most Prominent App in this space. They let you pay extra for intimate conversations or more romantic statuses compared to a friend, which you can have for free. Ali who are the typical consumers engaging in these products . Haleluya we really dont have really good information in terms of the gender brkdown or the different age groups that are using these. But we do know from external, external studies at have been done on this topic that, at least when it comes to replika, that a lot of the people that have been using these apps are people that have experienced loneliness in the past, or people that, more than just have experienced loneliness. Feel it a lot more acutely in their lives, and they have more severe forms of loneliness that theyre going through. Ali you talked to some users who really reported how they felt like they were making a real connection with these bots. Tell us about what those experiences have been, like those that youve reported out. Haleluya one person we put in the story, we spoke to him more. His name is derek carrier. He is 39. He lives in bellville, michiga and he doesnt use replika. Hes used another app called paradot that came out more recently. Hes had a tough life. Hes never had a girlfriend before. He hasnt had a steady career. He has a genetic disorder. Hes more reliant on his parents. He lives with them. So these are all things that make traditional dating very difficult for him. Recently, he was looking at this ai boom that was happening in our society. So he downloaded paradot and he started using it. Initially he said he experienced a ton of romantic feelings and emotions. He even had trouble sleeping, in the early days. When he started using it. Because he was just kind of going through, like, crush, like, symptoms. You know, when we have crushes and how we sometimes cant sleep because were thinking about that person. Over time, his use of paradot kind of tapered down. You know, he was spending a lot of time on the app. Even if he wasnt spending time on the app, he was talking to other people online that were using the app, and he felt like it was a bit too much. So he decreased his use. Ali the Surgeon General has called loneliness a Public Health crisis in this country. Is there a debate happening now about whether these bots are helping adess the loneliness crisis . Or are they, in fact, exacerbating it . Haleluya if you talk to replika, they would say theyre helping, right . It just depends on who youre speaking with. Some of the users that, for example, if you go on reddit that have reported some of their experiences with these apps, they say, you know, its helping them deal with loneliness, cope with those emotions, and maybe get the type of comfort that they dont really get in there human relationships that they have in real life. But then theres other researchers, people that have kind of expressed caution about about these apps as well. Ali what about some of the ethical concerns about privacy, about maybe using peoples data without their consent . What do those conversations look like . Haleluya theres researchers that have expressed concerns about, you know, data privacy. Or is the data the type of conversations that people are having with these chat bots, are they safe . In terms of, you know, theres a lot of advertisers that might want a piece of that information. Theres concerns about, you know, just the fact that theres private companies in the space that are encouraging these deep bonds to form between users and these chat bots and companies that want to make profits. Theres concerns about, just in terms of what this does to us as a society when these chat bots are formed to be supportive, to be a lot more agreeable. Right. And human relationships, we know that theres conflict. You know, were not always agreeing with our, with our partners. So theres challenges in terms of how this is shaping maybe how people think about real life human relationships with others. Ali haleluya hadero, covering technology and internet culture for the ap. Thank you so much for your time. Haleluya thank you, ali. John two historic milestones in basketball this weekend. Last night, lebron james of the Los Angeles Lakers became the first nba player to score more than 40,000 points in his career. He did it with this spinmove drive to the basket. And this afternoon, on a foul shot, Caitlin Clark of the university of iowa became the new alltime ncaa scoring leader, for men and women, breaking a record set more than a halfcentury ago by Pete Maravich at louiana state. Christine brennan is a usa today columnist. Put this accomplishment this afternoon and the player in perspective. How big of a deal is this and how good is she . Christine the person with the most points in the history of Major College basketball is a woman. And i never in a million years would have thought i would have been able to say that sentence. The fact that Caitlin Clark has come a long come along at this time in our nations history, you and i have to about title ix, we as a nation, we have fallen love with what we have created. The opportunity for girls and women to play sports. It would be inevitable that someone like Caitlin Clark would come along. A terrific role model, great person, and has had a run that we may not see in sports, mens, womens, basketball, other sports, inany, many months or years to come. Just this incredible ability to hit those threes. It is unfortunate it was a foul shot, but she had many threes in the game. And a big victory for iowa over ohio state, a rival day wanted to win the game on senior date. There was a lot going on. She has more games to go. She will put number even higher and may be out of reach for others coming after her. John you mentioned the significance a woman is now the alltime scoring leader. Talk about the fact that this is a record that stood for so long, more than half a century. Christine right. Pistol Pete Maravich, i remember as a girl watching him play. He was prolific, spectacular, he was exciting. In many ways, people have said to Caitlin Clark, watch videos of pistol pete because you are so much like him. That is a perfect analogy. And also the fact that we are talking there are people out there that maybe arent loving this. May be guys who are thinking, wait a minute here. You know what . The conversation has brought pistol pete back into our consciousness. Tragically, he passed away in 1988, 14 years before Caitlin Clark was even born. He was 40 years old. The fact that we are talking about him and bringing him back and telling kids about him is fantastic. Now this. These steppingstones in our nations history and culture as we look at the advancement of women in sports. And a male domain. Basketball has been a guys club, and a sense of, we talk about we dont use the adjective mens often when we talk about basketball. People talk about doing their bracket when there are two brackets. I would guess a lot of people will be doing a womans bracket this year. Nonetheless, click Caitlin Clark has been breaking through this with a smile and joy and happiness that has brought millions of people along for the ride with her. John she is going into the wnba draft. What is impact on the league . Christine i think
