Key travel isn't back to what it used to be, but it's moving down everywhere so apple at least isn't far behind. I went from a T series thinkpad to an M1 air and the keyboard was a clear downgrade, but in practice I find it to be "good enough".
Apple:
.7 mm - butterfly keyboard
1 mm - current mac scissor keyboard
1.3 mm - old mac scissor keyboard
Thinkpads:
1.8mm - T series thinkpads (aka the ones with the good keyboard)
1.5mm - last year's X1 carbon (the thin and light)
I know it's completely subjective, but I'm currently on a work provided 2018 mac with the 0.7mm travel and I despise it. I have far, far more typing errors on this keyboard than I do on pretty much anything else.
Same, I use a mechanical keyboard at my desk, and being forced to use the laptop keyboard would drive me insane. I spilt coffee on it and ended up upgrading to a 2020 Pro which (to me) is just barely bearable.
Typing on concrete - that's exactly right. I got awful RSI from the butterfly keyboard on my 2018 15-inch MBP. I had used previous MacBooks for nearly a decade with no problems.
Yes! Thought I was the only one. It was slick, good-looking, and typing was a breeze on those.
But it was super-problematic and had mine broken multiple times over the years. If they could make 0.7mm butterfly reliable, that would have been awesome.
