How is giving something, that is nondeterministic, access to your web browser a good idea? How do you guarantee that it doesn’t enter sensitive information without the user’s explicit consent? How do you guarantee privacy and security?

I’m skeptical, but I am genuinely asking and willing to listen.

IMO it’s really more of the same. There are plenty of new things to make, you can now glide around, and there is a central hub island to build freely on, but it’s still largely the same formula as the first one.
