Go get a job with an established company, then you can consider thinking about a start-up business many years down the road when you have a lot more experience and savings to drawn on (and/or more established credit history for loans.
The whole discussion in this thread is that now/(very soon) you simply won't have an opportunity to get a job "with an established company" because they don't need much workforce thanks to technology advances!
So you think they are going to replace the people who design water delivery systems, rockets, weapons, sewage treatment and routing, building specs? That's what your saying? Not in your lifetime or your grandkids' lifetimes, I have news for you.
What about doctors? Robot lawyers? Singers? Athletes? Sales and Marketing? How about government officials? The military? Teachers?
The whole idea of this is absurd. Like I said, they are only automating shitty jobs that no one should be aspiring to do nowadays.
