The development has been driven by the needs of Modular.

Mojo compiler is closed, the language development is quite open. Some of the proposed changes have been shelved or tweaked based on community feedback. However, you should understand that the compiler is closed to avoid design by committee and bike-shedding, Modular will and does veto decisions on core language semantics, see: https://forum.modular.com/t/canonicalize-apis-around-int/253...

The compiler is getting opened this August. I must admit, a lot of people who would be normally interested in the language are hesitant to poke at it with a stick with the current license (myself included).
The language has really great set of features and functionalities wrapped in a familiar syntax, I have zero doubt it'll reach mainstream adoption.
