The stage between super-humans and The Mind is really, really bad. I'm about to be able to unlock it now after 6 hours of just sitting on my ass leaving the game on and I'm not even sure it'll give me the boost I need to reach meta-humans in a decent amount of time.
The Universe upgrades don't even really do anything... 500x atoms or whatever is a drop in the bucket at this stage in the game and getting 10k T2 atom buildings is impossible.
