Yes, they hired him, at the end of the race, after he has done everything on his own without any kind of Google support.
On my book being committed, is paying for the race at the start.
When TF4S delivers even the half of what ML.NET or Julia allows for on Windows including IDE, libraries and tooling support, today, and they actually start doing a bit more information then what gets given to Python, C++ and JavaScript then they are actually committed.
"As for Google, I still don't believe that they are that committed as well, "
They have any approximately 10+ person team, many of whom are new hires from apple etc. Even for Google that's a decent chunk of change.
