I must be young at heart while >60 years old; my reaction was "why is everybody whining about it, it's pretty nice, I like it". Same with jj vs git, jj is amazing!
The annoying thing is that the latter group is over-represented in tech and a lot of core products like phones force people into that path. Most of the non-tech people I know couldn't care less about the latest iphone/android update,they just want the damn buttons to stay the same so they can do the stuff they were doing yesterday. But the only two phone platforms both change their UX regularly and users just have to go along with it.
For me, the killer feature is updating some commit deep inside some feature branch, and all child commits and branches get auto-updated, no more faffing with endless rebases. Also conflict handling is so much more pleasant than git's.
