OP's post reads like a marketing blurb.
To answer your question: No. But I have kids, and they do. Like everybody above is mentioning, there seems to be a target demographic for Roblox, and it isn't the same as the one posting here.
I though that Roblox was one game, but interestingly it's better described as a game platform. I'm sure a good bit of the next generation of software developers are going to have gotten their start working in Roblox.
Back in the day my game of choice was Warcraft 3. I was garbage at the main RTS game, but the "world editor" allowed for so much customization that you could spend all day playing games that were vastly different from one another -- all inside the War3 engine. Roblox reminds me of this. There are some genuinely fun games out there, as well as bizarre and weird ones. And chances are there's some kind of knock off Roblox version of many popular games.
It's not for me, but I can see the appeal. I'd rather my kids play things like "find the markers," "wormy," or maybe making their own experience (as the individual games are called) instead of something like Fortnite.
