I like this idea a lot! Looks like something that will be unavoidable eventually
One thing I'd note about getting funding is that the current budget might scare away investors in its current form. While I do see how a project like this would cost that much and even more, some brackets with lower values and goals for an MVP and more detailed budgeting would make it more compelling, specially for smaller investors too (and since this is a social network it could be entirely funded by its first users)
Great pitch with a lot of potential use cases!
