What hardcore singularity believers should consider doing

I should take as much long-term, fixed dollar debt as I can.

Get 50 credit cards in one day and go on to accrue as much debt as possible over the course of a few years. Give the credit card companies a temporary address and a temporary phone number such that you can lose their annoyance easily. Put half of your newfound free money into high yield investment opportunities such that you have a shot of paying it all back later. Use the other half to travel the world, become Enlightened, learn highly useful skills, and get yourself in a good position to make a lot of money or otherwise gain a lot of utility. Downsides: no mortgages, difficult to rent a house or apartment (but still not that difficult), if you want a new car you have to buy it with cash, some jobs will be harder to get (but it's not that big a deal), it might be difficult to move to a new country, it might disrupt your peace of mind, structural uncertainty, and goal distortion. I think a free 50,000USD or however much is worth those costs.

I would take it as a decent experimental result indicating that you aren't as confident in a 21st-century, world-revolutioning Singularity as you liked to think you were.

I did a little Googling. It seems that cats and dogs that are castrated do live longer than those that don't, so lower testosterone might be correlated with longevity. I think, though, that the effect on patients in mental institutions may be greater than on the population as a whole. Mentally ill, institutionalized patients are often violent. Castration would tend to calm them down. It would lead to less fights, less time in isolation rooms and being treated better by the staff. That would all contribute to longer lives on average.

In any case, even if castrated individuals don't live longer, it would FEEL longer.

Honestly, I would be very curious to know if chemical castration (which is apparently not as nasty as it sounds — I think I read that it results in no permanent physical changes and is reversible by discontinuing administration of the drug) would have positive effects on rationality. I can see how it might; considering that (as Will put it) your thoughts are bent by what you wish to signal, cutting out the drive to constantly signal reproductive fitness could remove a significant source of thought-bendage.

Not that I'm volunteering to try it, but...

Going by his comments history, he became even less creative as a troll and quit over a year ago.

Increasing your probability of living forever(/for a really really long time) still greatly increases your expected sex, assuming FAI can reverse castration.

It gives you a better chance of making it there.
