In particuar the notion of the quantum theory of immortality received a lot of discussion. Hal followed the absolute SSA interpretation, which means he didn't believe in the quantum theory immortality. However, if he's wrong, I hope he didn't stay locked in for long!
Problem is that instantly replacing said phone does not teach the right lessons to the kid either.
I first gave my son a mobile phone when he was about 10, when he started at a distant school involving taking public buses to get there. It was an old brick (late '90s nokia), and attached by a string to his schoolbag for the first few years. Even so, he still managed to lose it a couple of times (fortunately we always recovered it, even if it took several weeks).
Now at age 15 he's pretty good about it, so he gets a modern smart phone.
In another place I worked at, there was perhaps only a dozen coding style items, every developer had their own style of working, and the crazy thing was it worked. You got used to the other coders' "accents" after a while, and the good thing was you didn't need to think too hard about the coding standard, nor waste much time in reviews.
So yeah - it depends.
For many years, I've seen Windows share (as measured on various websites I own) hover around 70%, with MacOS climbing to around 20%. Linux has been stable in the range 5-10% - the remaining 1-2% is usually classified as "unknown".
My website data may be atypical, but it can't be _that_ atypical.
Fvwm2 does all I need, plus runs rings around KDE performance-wise. The only thing it doesn't do (which might be handy), is support multiple screens properly.
Still, as other posters have commented, the real reason why (some) physicists are mad, is the seeming giving up on scientific testibility. I think this is wrong - that scientific testibility is possible, in principle and practice, and the ontological benefits of a Mulitverse are worth it. I could recommend David Deutcsh's book "Fabric of Reality" for an excellent discussion, or my own book "Theory of Nothing" (gratutitous plug warning).
