I just hope intelligence doesn't fall to the merchants of Venice as Babylon once did. Smart people using LLMs can do some cool shit, provided they maintain the ability for critical thinking and problem solving.
Once those skills are lost (just like basic computer skills like... navigating through directories or installing an operating system) are lost, I think I will be glad to not be around to witness the calamities that will befall humanity.
Computers aren't the magical black boxes that people think they are. Our brains certainly aren't, either; but the extensive use of LLMs in place of cognitive human effort and discourse is going to see so much stagnation.
