I have been skeptical about all this, but decided to play with using ChatGPT for coding a task I had. It wasn't perfect, either in workflow or in final results but what was clear was that not adopting it will very quickly make you lag behind your peers.
I think the additive bonus is especially high for senior devs who are fast, in that those will be faster in grokking the generated code and better at guiding it to the right solution.
I guarantee you that in five years anybody who cares at all about their productivity will be using it constantly in their workflow, probably much sooner.
