I'm someone who really enjoys the process of learning, and struggling, even when it doesn't immediately get me things. This sometimes pays off, but it also means I'm often slower at the start (which can be bad for jobs).
One thing I kind of argument I missed in the article however, is that I would also apply this learning and struggling to LLMs themselves. There is knowledge to be gained on how to use LLMs as a tool. Maybe similar how you can use Google or a calculator as a tool, while not losing the understanding yourself. I do think the chance of knowledge loss is more pronounced for LLMs as they can cover so much.
I also think Bob (from the article) will likely learn better how to use LLMs than Alice. Sure he might not understand physics as deeply as Alice, but he might learn how to write papers very well with LLMs that get accepted for conferences and that build his career.
