Sure, you can create any kind of arbitrary set of rules you want. We could have programming contests where, say, code-coloring and auto-indenting editors were banned. We could ban the use of auto-complete in editors. We could ban the use of certain compiler flags--or ban the use of compilers all together.

But the reality of capitalism--nay, the reality of all life on this planet--is that unless you can continually increase your productivity, you are going to be obsolete. Companies don't care about "cheating" with LLMs. They just want super-productive programmers.

Frankly, I think schools should be actively teaching their students how to use LLMs. And then raise the bar on how much we should expect, say, High School Students should learn in a semester. We have stories of employees becoming 3x, 10x more productive using LLMs. What if our high school students were learning 3x, 10x, more per semester than they do now?
