I can do things as one software engineer what 10 years ago a whole team needed.

If chatgpt can do things you would have given an junior or assistant and it's now faster to just do it yourself it will have an impact and it might raise the bar.

I would neither under or overestimate what it can replace in a few years.

And surprisingly a lot of time and energy is used to teach people old things just because they also need to learn.

It just might be e easier to teach it once to chatgpt or whatever is next, than people.
