As a middle-aged developer, I've seen a lot in my lifetime, but I believe that right now, even though in some ways I'm much more hopeful for the future than I've ever been, I feel like there are many huge time-bombs out there in the world that make focusing on a startup just to have a chance to become financially successful a petty and, for some, a possibly futile ordeal.
For example: political divisiveness/change/chaos, scary world leaders and potential world leaders discussing/threatening/testing nuclear weapons, wars for and against religions involving terror, causing mass death, spawning racism and restricted freedoms, other random shootings/acts of violence, discord and violence between people that are racially targeted and those who want to serve the public to protect people regardless of their race, terrible diseases/epidemics some without cures or growing resistance to cures that we've long depended on, weather related natural disasters, economic troubles, etc. The list goes on and on.
Given the climate of the world today and all of our problems, what things do you want to see- not just in the startups that you and/or YC as a whole want to help, but across the board? And what do you say to those that think that just don't feel safe enough to invest the time, money, and effort on a startup which has a greater chance of failure than success when they could just be working a stable job to try to save enough to survive what is ahead?
