Are you even reading what I'm saying?
He got the build early because he used Clone Armies and Parlimentary System which are both individually strong and synergise well together.
If you only run a normal, non-busted slightly unity focused build, Telepaths on their own won't turn up until they're too late to be gamebreaking (they'll still be strong, but hardly the gamebreaking powerhouse everyone keeps talking about).
If you only run Clone Armies + Parlimentary System it will get you to your ascension way earlier than normal, which is extremely strong no matter the Ascension you choose.
Therefore trying to pin all this on Telepath spam is nonsense.
If both players run a normal, non-busted build, then Telepaths' clear 3-fold production advantage over other ascension paths' job output would cause the psionic player to rapidly pull ahead again.
Alternatively, if both players were playing a non-normal, busted build, then telepaths' clear advantage would do the same.
If you start from the assumption that they're on equal footing when they ascend, then the massive advantage from ascension on is still a massive advantage.
Again, this is almost certainly getting patched soon. But I'm objecting to the argument here.
In general, something like "a tryhard player could have conquered a neighbor and already locked in enough of an advantage to win the game by then, so it doesn't matter" is a
terrible argument.
It doesn't reflect the way 90% of the playerbase actually plays the game.
It boils down to "everything after 2250 is just power fantasy and can be completely unbalanced without issue".
And from the second can be inferred: "this argument is useless noise, because the people who it applies to
do not care about the topic being discussed (balance after 22XX), and everyone else does not care about the playstyle this argument applies to".
It is a self defeating argument: if it's accurate, you shouldn't bother saying it, because whatever thing is being discussed can go one way or the other and not impact your play in a meaningful way (or, so claims the argument).
