Doing nothing does not drive self improvement, I can't get stronger sitting on the couch watching videos on YouTube about weight lifting, even if I did type in the search term.
It's not like watching others lift, it's like having a sparring partner. ( A very fast, slightly stupid sparring partner...)
Coding a button isn't the part of software development that's intellectually stimulating, so I am glad we have robots to help us speed it up.
I feel like you're coming from a place of disliking chatbots and then working backwards.
Tools don't improve skills they replace but, at the same time, are those skills that are being replaced important to practice? If you've worked even briefly with vector math or game programming you know sqrt(2) is 1.41 being able to summon that value at will is essential if you're regularly doing vector addition - but sqrt(23)? Probably never going to come up.
At the end of the day we need to decide whether these tools are helpful or not - in the very limited scope of UI building I think the answer is yes... a lot of front-end surface-level development has one right answer. For other things I am skeptical - and even for front-end work a developer that is considerate with their CSS classes and tag nesting will be a darling of the UI team compared to a developer that gets it to look right but does so with code that's difficult to understand or modify.
Are you suggesting that you wouldn't want anyone (or anything) to suggest improvements for you because then you would not learn yourself how to improve?
You can call productive if you want, but sounds pretty far from self development to me.
Learning is easy. It's just learning.
There’s plenty of woodworkers that work exclusively with hand tools for the joy of it and that where a lot of programming will be a decade in the future.
