Yeah all I have left are the 50k creativity and 70k op things and as far as I can tell my only way to gain trust is the paperclip production bonuses and lol that's gonna take awhile.
I don't know if I'm simply not understanding quantum computing or if it's really just not very useful. I have all available chips, but I can't seem to ever raise it more than ~2k past the maximum before it starts to fall again. At 61k maximum, that means I'll still need to idle until I get 7 more paperclip production trust increases to buy the 70k ops thing. It looks like that's going to take forever.
I'm in the same boat as you are. It was useful for spamming modeling but I have little use for it anymore. All of my spend money for +1 trust upgrades are also gone.
So I guess protip to anyone before this point regarding spending Trust: make sure you can get to 70k memory ---
