"Helping rich people get taxis easier". As a Lyft and Uber driver, I count among my rides: getting a rough looking fellow (who has spent years in prison after accidentally killing someone in a bar fight) get to the only job that would take him - affordably and on-time (he would have been fired otherwise). I've given an enlisted navy family from Oklahoma (husband was deployed) get home from a late night run to a dista…
The explicit inspiration for Uber's founding was as a "limo timeshare service": http://newsroom.uber.com/2010/12/ubers-founding/ I"m glad that some people are also getting easier taxi service. But having worked in in SF since the last bubble, there is definitely an intense focus here on solving rich-people problems; when they serve others (e.g., struggling felons and young military personnel) it is often, at best, a…
Of course, funny enough, many of the same people that complain about this will simultaneously tell you how many unexpected discoveries came from seemingly abstract government funded projects (from pure research that has no clear immediate benefit to huge projects like landing on the moon). Such side effects are not exclusive to government projects however. So too the problems we choose to work on voluntarily. I think its not necessary to get into the great many benefits studying the heart for the sake of heart disease have given the medical community in general. Another example I like to use is how the gaming industry has led to the development of super powerful graphics cards that now have enormous medical uses. Personal computers themselves have enabled so much for our society. But before there could be a 200 notebook there had to be a 10,000$ rich person computer.
In my experience, it is a trap to worry about what is "impactful". You will make a much greater impact on the world working on what you're good at and what you enjoy, because you have more control on making that GOOD than making the alternative impactful. If you look at the history of truly amazing discoveries, they are rarely straight forward, so its a better bet to invest in what you like than what you think is important.
