Humans acting with intention do it a lot less. The difference is that LLMs don’t act with intention.

No, the difference is in the education/experience of any given human, which is mostly gated by age. Like you'd generally expect someone young to make a lot of mistakes, and as time went on they'd learn and make fewer. Pretty much the same with LLMs, which have been around for... a bit over 5 years now? What would you expect of a 5 year old acting with intention? Or 10? Or even a 15 year old?
