If you've used Google Chromecast or Google Chrome, a Tesla, or an Xbox, keeping software up to date isn't the chore it once was. Or you have to update to go online/have the car drive. The "guarantee" is that the other players who were too aggressive and did bad had to exit the industry. Uber killed a woman and exited the industry. Cruise dragged a woman 20 feet and lied about having footage of it, and exited the industry.

So you ask what's the guarantee, and the guarantee is the same as when Google came out with Gmail, and everyone said that's stupid because how are you going to read your email when that website is down, so then they made it so that website doesn't go down.
