Say we assume Goku will magically know to snatch Thanos's gauntlet and immediately speed blitz him, even though he's never done this before.
Thanos says he turned off the sensory input from "time, space, reality, thought and the soul" and only retained his raw power. This would obviously impede his reflexes/reaction time in addition to his prescience.
Do you seriously think Goku has faster reaction speeds than someone who has absolute power over thoughts and the mind?
Do you seriously think Goku has faster reflexes than someone who is infinitely physically powerful/fast/etc.? (he obviously wasn't using the power gem to its max potential in that scan or he would've killed Captain America with a pinky jab)
Do you seriously think Goku can move faster than someone who has absolute mastery over time and space, e.g. the dimensions through which Goku has to move?
Likewise, the fact that trying to take out Thanos with time travel failed because it was like "trying to drown the ocean" demonstrates that his defenses actively exist and he doesn't have to "bring them up" for Goku to preempt.

Also, in that scan Silver Surfer clearly attacks Thanos when he isn't looking, so it tells us nothing about his reflexes even with those restrictions on his abilities.
Thanos with the Infinity Gauntlet is literally someone who has near-absolute mastery over every aspect of reality itself. If you were to drop him on Earth today there would literally be no way in principle that you could distinguish his powers from those of any of the described Abrahamic Gods. Goku is a powerful dude who can fly (incredibly) fast and shoot (absurdly) powerful energy beams. There's absolutely no comparison between the two.
