I have been at 600-800% over capacity since I started to play again, but the only skills I could bear to unlearn were cooking skills. I use all the rest of them, so they are essential. So demand will continue to outstrip evolutionary supply, I guess. It certainly has provided me with plenty of prep time, collecting resources to apply once my learning comes to "skillition".
I don't know, I guess since I apparently keep my brain inside a rock with spectacles, I don't have to face any personally disastrous consequences, which would most certainly occur in any other life situation where demand outstrips supply by those percentages. I mean, I would think my rock would have exploded by now, or fomented a desperate rebellion, or oranized with other rocks and gone on strike. But he seems to totally dig it, go figure.
Brain capacity 56/45 skills, 71% time penalty, and I haven't purchased many brain capacity cards yet. I don't know how to cook (anymore) and I wouldn't bother with any AK except you need AK3 to feed sloths. also, no croppery and minimal gardening. I don't recommend it to everyone, but just to point out that no, you don't need to know everything.
WalruZ, there's need - and then again, there's need.
Thanks for the replies all, I'll just keep shuffling 'til I get more brain cards. I'm only at 36/27, with a 55% penalty - so not bad. I'll work on 4+ hour skills for a while and hope I can grab enough cards to catch up to myself.
