She doesn't have no gamerscore, she has like 1200 because her account was set up like a month ago and she has some token achievements she probably didn't earn.
It's not about the amount or how much. Phil Spencer had a lot because he was a gamer and an exec. He was one of us, more or less, he played games and he liked working in gaming. I don't agree with all of his gaming opinions (in fact, mine are fairly uncommon, so that just comes with the territory).
I have a pretty high amount just because I've been gaming since before most people here were born. So I've had an Xbox account for something like 20 years. I've only really gone after a few achievements. Mostly I just play. Over time, that builds up. I've worked longer hours than a lot of people, in jobs most people are too good to do. "Work hard, play hard" may be a cliche, but I don't smoke, I don't drink, I don't do recreational drugs, and I don't engage in extramarital affairs. I'm not a woodworker or a gearhead — gaming is my hobby. It's what I do to relax at the end of the day, if I have time. If I don't have time for a more "serious" game on the Xbox, I fire up my Switch and dick around on my Animal Crossing island. I've already rolled the credits (several times, long story, AC fans get it) but it's somehow fun to just run around and talk to animals and catch bugs and shit. Either way, it's what I do and I've been doing it for a long time.
I just think someone who's been playing games for years would make a better executive of a company's gaming division than someone who's never picked up a controller. LOTS of people play games. If someone never games, that says to me they don't like gaming — and they possibly don't like gamers. It's not a good look. Especially juxtaposed with the rise in AI and Microsoft bringing an AI exec in to run Xbox. It's not a good look at all.
PC has been coopted by Microsoft and gamers to mean an x86-64 box, and it kind of applied to Intel Macs since they could run Windows and could have graphics cards (specifically the Mac Pro which had PCI-E slots and was really just a traditional PC that happened to be macOS certified and shipped with that OS.
So yes, it's a specific kind of PC. It's like saying a truck is a car. Yes, technically, if you wanna split that hair, but it's not like people calling it a truck are wrong. And maybe they are proud of what they have, but they're also just trying to be accurate and not disingenuous.
By saying it's a Mac, I avoid people suggesting I run tools only available on Windows. However, I attract haters. I'd rather be concise and informative than well liked. I don't care that you or the next guy doesn't like Macs, but yes, I'm going to call it what it is, because while it's also a PC, it's different enough and I'd like to avoid the chain of conversation that comes with "just use X app" and then I have to say "it doesn't run on my platform" and then we're back to here with the haters. So I just cut out a step.
