You need some extraordinary evidence to claim things like that.

To stretch things a bit, it's like saying, while male dominated the field of engineering in the 60s (and still do), it was exactly that kind of environment that made it possible for humans to get to the moon. Can you actually prove it? Really?

It's hard for me to imagine using git will slow down kernel development compared to sending patches in emails.

No. It's a legitimate possibility. Maybe it wont happen. But maybe it will. There's a reason that military training is meant to be hard though, and not filled with comfort and affordances for personal feelings.

No human has been back to the moon since that male dominated field sent them there. And when they added women, they couldn't produce a shuttle that could work without huge budget overruns, or reliably. And the only example of a real surge in a return to space, is run by an asshole dictator at Space X.

No, that definitely worked out great. It was created by a gruff guy who was an asshole to everyone, and wrote the basics of Git by himself in a week.
