To literally any Xbox gamer reading this: how do you feel about having a higher Gamerscore than the (new) CEO of Xbox? Rhetorical question. I don't expect (or have any use for) an answer. Rather, I just want you to think about that. You might not be qualified to be a CEO of anything. But you undoubtedly know more about gaming, and what Xbox players want, than this person who has only recently taken up gaming to say she has (or maybe she has assistants playing on her account for some fake cred).
Mine's not worth bragging about, but I'm sure it's over 100k. That used to mean something. Now it just means Xbox has been around for 20 years and you've played a lot of games on the platform. Either you platinumed 100 games, or you played a lot more (including Arcade titles which were capped at like 200-250GS, IIRC). I actually only have like five platinums. Fallout 3, Fallout 4, Oblivion, Skyrim... maybe one other? (Bethesda games are easy to platinum.) (Yes I know platinum is a PlayStation term. We all know it means to get all the achievements.)
Achievement I'm proudest of? Rockband 2, Bladder of Steel Award. Complete the "Endless Setlist II" (all 84 songs on the disc!) without pausing or failing at any difficulty other than Easy, on any instrument. I did it on Medium Vocals (easiest way really). Regardless of instrument or difficulty, playing the ESL2 without pausing takes 6 and a half hours. It takes longer if you fail, obviously, but once you fail, you may as well stop, since you're out of the running for the achievement.
Until AI can game for you, I don't think Sharma is going to get 100k GS, or do something like the Bladder of Steel Award that requires more than just casual interaction with a software title.
On my Mac, I just use whatever the default static wallpaper is. Or I pick one of theirs. I always have widgets covering my wallpaper and I don't know how to easily see what it is (short of → Settings → Wallpaper), but I think it's like a forest/hills. On my MacBook it's a lake.
On my phone, I have a Star Trek theme. LCARS (the OS on Next Generation) lock screen, and one of the ships (I think it's Discovery, I never really look that closely at it) warping up toward the top with the trails down between the icons.
I mostly don't care what the wallpaper is because I never look at it, but I'm too proud to just have it black (nothing there). I know that's an option on Windows (no wallpaper, and there's a setting for the desktop colour), but I'm not sure about Mac or iOS.
I almost envy people who have "cool" wallpapers (my wife has a bunch) but I mostly can't be arsed. Like... I wouldn't mind having digital frames with rotating wallpapers or fan art or whatever. But my desktop? It's a workspace and I have work (or "work") covering it all the time.
