Every race can get to 4k a turn using Ac + knowledge tile/sci track. Or settle for 2K and +2K action until they can get 2RL and/or some other combinationBut you are giving up other stuff early game going for this. Expansion opportunities, early scoring rounds, income
Imagine going up knowledge track first 2 rounds but have almost every planet next to you get taken by expansionist races. Now you need to get up pass Nav2 to expand pass your R1 buildings, you probably won't fair very well in the endgame scoring
It's all a balance. I will say that 4K from turn one can be a solid opening but whether or not you go up sci track for even more or not is very situational.
