The can for sure maintain and iterate on smaller projects -- which millions of people are happily feeding into them as training data.
Going from a project with 1,000 to 1,000,000 lines of code is a tiny leap compared to going from 0 to 1000. Once your argument is based on scale then you pretty much lost to the robots.
I'm not saying they are going to invent some free energy source (other than using humans as batteries) anytime soon but when the argument is "you're going to be blindsided" and the response shows, and I'm not trying to be insulting or anything like that, willful ignorance of the facts on the ground I'm going to say you probably will be blindsided when they take your app writing job or whatever.
I'm not attacking you at all just saying that there's a bunch of people who chose to keep their heads in the sand and hope this all just goes away.
