As someone who is relatively young and thus inexperienced, this is to a large extent the million dollar question. Or, rather, the question of which skills are important is.
A lot of the people I know who are just a few years younger than me learned / are learning at university and even grade school with the use of LLMs. This, to me, is terrifying. They are forming a foundation of knowledge and skills so fundamentally different to that of people my age and older.
This is not the difference between googling vs. finding a book in the library. This is the difference between being forced to think through a question and answer vs. not thinking through it at all.
I fear that the prioritization of LLMs in so many aspects of society and the workplace encourage this, and that we don't yet have enough guardrails to protect ourselves against this atrophy.
That is a long way to say, I also tend to fall on the side of caution. I do my best to use LLMs only for things that I can not do AND do not feel that I am likely to need to be able to do in the future. Or for things that I am super confident in my ability to do and thus know right from wrong and can just use LLMs to speed myself up.
I think that as long as people have a strong foundation (though it is unclear in what is important..) than using LLMs is not the end of the world. I am more worried about a future in which we won't have a useful BS meter to check them with.
