Being able to think faster is something I try for already, with the means available to me. (Nutrition, sleep, mental exercise, I've even recently started trying to get physical exercise.) I actually already prefer healthy food (it was a really SIMPLE hack: cut out junk food, or phase it out gradually if you can't take the plunge all at once, and wait until your taste buds (probably actually some brain center) start reacting like they would have in the ancestral environment, which is actually by craving healthy food), so the only further modification to be done is to my environment (availability of the right kinds of stuff). So obviously, those in particular I do want.

However, I also believe that here lies the road to ableism. EY has already espoused a significant amount. For instance, his post about how unfair IQ is misses out on the great contributions made to the world by people with very low IQs. There's someone with an IQ of, I think she said, 86 or so, who is wiser than I am (let's just say I probably rival EY for IQ score). IQ is valid only for a small part of the population and full-scale IQ is almost worthless except for letting some people feel superior to others. I've spent a lot of time thinking about and exposed to people's writings about disability and how there are abled people who seek to cure people who weren't actually suffering and appreciated their uniqueness. Understanding and respect for the diversity of skills in the world is more important than making everyone exactly like anyone else.

The above said, that doesn't mean I'm opposed in principle to eliminating problems with disability (nor is almost anyone who speaks out against forced "cure"). Just to think of examples, I'm glad I'm better at interacting with people than I used to be and wish to be better at math (but NOT at the expense of my other abilities). Others, with other disabilities, have espoused wishes for other things (two people that I can think of want an end to their chronic pain without feeling that other aspects of their issues are bad things or need fixed). I worry about EY taking over the world with his robots and not remembering the work of Erving Goffman and a guy whose book is someplace where I can't glance at the spine to see his name. He may fall into any number of potential traps. He could impose modification on those he deems not intelligent enough to understand, even though they are (one person who strongly shaped my views on this topic has made a video about it called In My Language). I also worry that he could create nursing homes without fully understanding institutionalization and learned helplessness and why it costs less in the community anyway. And once he's made it a ways down that road, he might be better than most at admitting mistakes, but it's hard to acknowledge that you've caused that much suffering. (We see it all the time in parents who don't want to admit what harm they've caused disabled children by misunderstanding.) And by looking only at the optimal typical person, he may miss out on the unique gifts of other configurations. (I am not in principle opposed to people having all the strengths and none of the weaknesses of multiple types. I'm becoming a bit like that in some areas on a smaller scale, but not fully, and I don't think that in practice it will work for most people or work fully.)

Regarding what EY has proposed that I don't want, on the catperson post (in a comment), EY suggested that we would have some sort of compromise where we lowered male sex drive a little and increased female sex drive a little, which doesn't appeal to me at all. (Sorry, but I don't WANT to want more sex. You probably won't agree with this argument, but Jesus advocated celibacy for large swaths of the population, and should I be part of one of those, I'd rather it not be any harder. Should I NOT be in one of those swaths, it's still important that I not be too distracted satisfying those desires, since I'll have far more important things to do with my life.) But in a cooperative endeavor like that, who's going to listen to me explaining I don't want to change in the way that would most benefit them?

And that's what I can think of off the top of my head.
