"Keep paving forward" can sometimes be fruitful, and at other times be an absolutely massive waste of time.

I'm not sold on LLMs being a replacement, but post-secondary was certainly enriched by having other people to ask questions to, people to bounce ideas off of, people that can say "that was done 15 years ago, check out X", etc.

There were times where I thought I had a great idea, but it was based on an incorrect conclusion that I had come to. It was helpful for that to be pointed out to me. I could have spent many months "paving forward", to no benefit, but instead someone saved me from banging my head on a wall.
