Land himself has suggested a very anti-human solution to the problem of "IQ shredders":

"The most hard-core capitalist response to this [IQ shredders] is to double-down on the antihumanist accelerationism. This genetic burn-rate is obviously unsustainable, so we need to convert the human species into auto-intelligenic robotized capital [a]s fast as possible, before the whole process goes down in flames."

Thanks, been awhile since I read it.

I think the only solution is territorialization if you want to preserve the human. If you don't care about that (or think that it's not possible anyway), then yes, accelerate.
