I'd heartily contest this, from a technical standpoint.
If there is any slowness in responding to high speed changes
in operating, it's not the computer but the mechanical elements. While
this is unfortunate, computer or no computer, mechanical devices
can be slow at making positional movements.
I can't think of any blindingly-fast responding elements in
any carb, however. If you feel that computer controlled systems
aren't as fast as they could be, that's another discussion, not
one that really belongs in one comparing it with carbeuration
systems.

Preprogrammed logic? Like... carb settings?

...which essentially means it will ignore things like the
oxygen sensor. How many LBC carbs do you have that listen to
an oxygen sensor? Remember the context of what we are
discussing here.

Echoes of what I am sticking to as a theme, you don't
see people who really know newer systems making such
comments.
