to build vacuum especially with a supercharged engine.
“Boost” engines don’t have usable vacuum.
Honest question that you “may” have just answered.
I’m pretty certain that it’s been proven that a “human” driver can not shift as fast as an automatic transmission.
IIRC, it was Nigel Mansel, driving for Ferrari at the time that destroyed the field with an automatic transmission.
Your statement makes sense if applied to “Drag racing”.

No, it applies to any supercharged or turbocharged engines. If they have positive manifold pressure (more air then the engine is naturally trying to pull in) then they can't have negative manifold pressure (vacuum).
IOW: Boost pressure is the opposite of vacuum.
It has nothing to do with transmissions.
