Urbit
I have seen Urbit a couple times but never really understood it.  From the "Understanding Urbit" page ->Imagine that you can login from anywhere with one name and password.>And when you do, your entire OS appears.>Inside is your whole digital life. All of your communities, conversations, and connections. All of your biometric data and devices. Your entire personal archive in one place that’s secure, private, and designed to last forever.What does this mean?  My whole digital life?  It sounds like I'm signing in to a VPS from which I access all of my digital life.  Is that it?  Do I get a VPS?That seems kind of like what I'm getting.  The first line on urbit.org is "Urbit is your last computer" - but I don't see how I'm buying a computer, for a one time fee, for life, without paying a ton of money.I see this website [1] has an Urbit "Planet" available for .04 ETH, or about 6 USD.  Could I get a life long VPS for 6 dollars?  If so, I'd definitely be up for it.  If not, what, exactly am I getting for 6 dollars?The page "Understanding Urbit" also says that Urbit OS "can never show you ads".  What does that even mean?  It can't run Chrome?  The OS can't show ads?  Any image or text can be an ad.  I don't get it.What I would like to see is a simple explanation of what Urbit is.  Maybe a video, where someone logs in to Urbit, and interacts with it in someway, doing something that can't easily be done in some other way. I'd like to know the difference between planets, stars, and galaxies.There has to be a better way to explain this.1 - https://opensea.io/assets/0x6ac07b7c4601b5ce11de8dfe6335b871...
