The youth does owe a debt to preceding generations... for their innovation and tenacity. Now, that onus falls on the young to usher in the next era of progress. This is likely to be an incremental rather than an overnight revolutionary one, and such has been the trend through most of history.

One of the broadest fields in which the youth can go about making these smaller changes is tech. As we move further into a digital age, we discover the various shortcomings of devices and softwares we so heavily depend on.
