How could you recapture the essence of old Claude?

I remember Claude being way more interesting a few years back. It wrote well, had a pleasant personality and was genuinely helpful. Nowadays Claude is a weirdly snarky back-talking and obnoxious. I’m the root of it is the fact it’s shifted from a bit of a curiosity to a programming tool. It’s less a language model and sort of now a wrench with writing capabilities stapled on which is a shame.

Any way to sort of get that “this 97 year old AI writes the old way” feel? If you have something, than you!
