I would argue that shipping to a limited test group qualifies in terms of measuring velocity, which is what the OP said they were impressed with.

Launching to 10000 people vs 10000000 is a matter of scale (which is still important, but not the same thing as), not velocity.

There's no reason to believe that what they're testing right now has any relation to what they show in the video.

i didn't see a place where they said they had 10k users already

Microsoft employs somewhere above 200k people. 10k is only a 5% internal rollout. That seems entirely doable without any fanfare.

The numbers are also completely made up, used to illustrate the point. Launching a product to X users is different than scaling up to X*1000 users, if that makes you feel better.
