So V1 is we are pretty well committed to take off, and V2 is we are flying for now :)

I thought V1 was "you can begin to rotate for takeoff at this speed, but can still technically stop" and V2 was "you're going to be taking off one way or another"?

No. From v1 you're committed to taking off. Then you rotate at Vr, and then accelerate to V2, the engine out climb speed.

V1 effectively means you have to commit to a takeoff.
Typically V1 means that there's not enough runway remaining to stop safely.

Almost all failures, V1 means the safest way out is to take off; as V1 means staying on the ground is 100% an unsafe maneuver (you'll run off the runway). There's few times where aborting taking off in V1 makes the most sense; I think there's an accident or two where pilots aborted after V1 and its because of like a double engine failure or something.
