I could hire 50 juniors that can code tomorrow if I wanted to. But even with an unlimited budget, finding good devs that can make it through a 2 year project without coming out of it with a big ball of unmaintainable shit is difficult.
The gulf from beginner to expert is already big, and the more crutches you use early on, the bigger it's going to get. There's a lot of people that wash out of the industry before they reach the point of being able to comfortably build good software (and be solely responsible for it).
I think copilot is another item in a long list of things that's good for big businesses (who optimise heavily for getting passable results with 1,000 mediocre devs instead of 50 good ones) and terrible for individuals in the long run.
