One thing that concerns me so far is that nothing put out by Mojo or said by any of the Modular leaders indicates that the language itself will ever be open sourced. The Mojo FAQ says:

"Over time we expect to open-source core parts of Mojo, such as the standard library."

In the most recent keynote, Chris Latner said the standard library will be open-sourced starting next year. I have never seen anything about the actual rest of the language. I worry that they don't actually plan to open-source all the core parts of Mojo and they're just letting others put words in their mouth to hype up the language.
