It can be massively over hyped for it's current capacity and decimate the white collar work.

A lot of the difference of opinion is down to their point of view. At my dayjob, LLMs will not live up to anything because the enterprise is not structured to take advantage of it's strength. That's unlikely to change within the foreseeable future.

I strongly suspect you mostly talked with people coming from just such a background, because it's hard to go beyond our own bubbles

It takes a lot of time to successfully deliver a product. Even at the more "extreme" end of expectation - like saying it's a X10 multiplier (I'd disagree on that, it's more like 0.5-3 - depending on the type of work you're working on) you'd still need multiple years to go from first line of code to displacing established players. Things just don't change that fast.

The irony here is that you are correct in the original sense of the word "decimate".

However, in my lifetime I've never seen someone both understand the original meaning of the word "decimate" and use it as the ancient Romans intended.
