Elon Musk appears to have changed his voice!

What is happening here?

He is proposing to make everyone on Earth rich? That sounds rather stupid and not the kind of thing Elon Musk would normally say.

Well that's because this is not Elon Musk, it is a hijacking of a presentation he made to associate his public persona with an app that cannot possibly do what is being claimed. This is a surprising move by these people as the light it will shine on their operation if Elon Musk sees this will surely be unwanted.
