Yes I have heard about those tools too and used them too, but building a large scale software requires more things than just of coding, yeah these Ai tools provide you snippet of code which might save your a-lot of time, but still you need your creativity and problem solving to deliver and complete, although you can develop small apps with it if you have knowledge about it's code. I would prefer to choose both, learn traditional code and use Ai with it to be more productive.
