If AI is the high end of programming, then it's the equivalent of saying that a recent manufacturing grad can't build their own car assembly line and has to go to work for Toyota, Honda, et al.

Barriers to entry at the "top" of industries are generally higher than lower down.

I'm sympathetic to the sentiment.

Consumers might benefit from the conglomeration more than from a lot of independent groups each reinventing the wheel or spending resources on duplicative infrastructure.

There are trade offs of course. In particular, I really don't want one single ML platform to have all my data and know me that well.
