you are oversimplifying things and ignoring a lot of variables.

just to illustrate a point: on a sufficiently large map, i could have four times as many workers by the time your first set reaches my spawn.

if i'm playing Protoss against a Terran AI, i have an added advantage of worker regen without having to stop attacking.

This is already an infamous strategy (worker rush) and it os easily countered as long as you have all your workers united and attack at once (not much micro can be done at that point, and the numerical advantage trumps that... unless you're playing protoss and constantly trying to replenish shields, and still!).

Also, I'm pretty sure this is not something that DeepMind would do to "solve intelligence".
