I agree with the whole bit about "power users" being... let's go with "misguided" here, but this:
Let me be blunt: macOS is an engineer's machine... I spend 90% of my day in terminal windows on macOS, using make and compilers.
...Okay? You realize you can do that on Windows, too, right? Or Linux, or BSD, or...
And this bit:
Virtually nobody in any form of advanced engineering uses Windows.
GTFO of here with that BS, what could possess you to make such a bullshit claim... oh.
shows that you have never worked in Silicon Valley circles
You're just one of those people that thinks your particular slice is the center of the universe. My dude, there are a shit ton more engineers out there in a ton more disciplines than just "software engineer" and the user population you're talking about is a small percentage of the whole.
