Long thread to skim, but interesting... It just seems like people who have to show up at a physical office due to the nature of their work or culture of their company, are cranky about those of us who don't have to.
1. I'm strongly guessing the ML guy from start of thread is doing just fine, and can go on permanent vacation, or get another job in 5 minutes. His life's choices are his life choices, it's not possible to extrapolate someone else's priorities to what any individual feels they should be doing.
2. Unless you've been there a long time, or your skillset is super-important ... Apple doesn't really pay that well. It could be said they're not very competitive. If you work at Apple as an engineer on iOS then that's something cool, because you're working on what's arguably the most important and profitable piece of tech on Earth. If you work for Apple doing 99 other things, then you're either replaceable, haven't been there longer than a few years, or odds are you're grinding along in a "high paying, dead-end job." I know quite a few people who work at Apple, and... it's just a job, "growing old, watching 20 person teams become 300 person teams making a mess, waiting for my options to vest." And quite often, you can go do a variant of exactly the same thing, at another co, while making more money and sitting around in your pajamas all day ... so why wouldn't you?
The people with all the enthusiasm often lack the skillset to replace the people whose lives they're judging.
3. IDK, it's the big shiny Uber-expensive mothership, finished right before COVID hit, so... they need to fill it up with something. Perhaps they can get some holograms of people walking around, grow goats, open an upscale homeless shelter, ya know, stuff that demonstrates how committed to ESG Apple is and their great love of all humanity.
I wouldn't ever show up at an office, because... I don't have to

I've worked from home for over a decade, long before COVID hit. Post-COVID it just means I don't have to drive to an airport, grow old and die standing in lines, get on a plane, fly to some other location, often located in another country, just to have a stupid in person meeting that lasts for 1-3 hours, followed by dinner, followed by the after-party (where 95%+ of all business actually occurs), followed by... I mean, I don't care, just open Zoom. Please wake me up when we get teleport.app and I can go straight to the after-party, can't be bothered before that.
