Let's see, they have so much technology that it's not broadly used. Like Mozilla Hubs, for example.
This platform is wonderful.
Many people use Mozilla Hubs to host classes for students, or seminars for businessmen, etc...
You can literally just open Blender and make a room of any level of complexity and explore it with your friends.
It's possible to materialize any object that can be digitally represented.
This kind of project (and many that are just not on the surface) I think will take the lead with Mozilla in the next few years.
We will see.
