holy fuck, Yud criticizing Banks is fucking exhausting, and I keep getting angry seeing this barely readable shithead try to tear down the work of a sci-fi author he clearly doesn’t like because people keep bringing up the Culture novels as a counter to his horseshit, and because they’re more fun and fulfilling to read than Yud’s nonsense ever will be

so I tapped out early and quote mined the 400 years part:

They live, in perfect health, for generally around four hundred years before choosing to die (I don't quite understand why they would, but this is low-grade transhumanism we're talking about).

yud. buddy. that novel explains why they would in the same chapter that describes a Culture citizen going through with the voluntary decision to die. it’s boredom. the major motive force behind almost everything the Culture does is boredom, because its constituent beings want for nothing. the civilization as a whole knows that existence for human-like beings becomes intensely, painfully boring (just like reading yud’s output!) around the 400 year mark, and the Culture has both removed any stigma around voluntarily ending a painful existence and any reason to prolong it past your own comfort. after that, you can enjoy an afterlife of being acausally pampered by every networked Culture Mind.

there’s even a version of the voluntary death and afterlife process for entire galactic civilizations called Subliming, where every natural and artificial lifeform in your civilization becomes a singular being of pure energy and transitions into another dimension. just like with uploaded organic beings, Sublimed civilizations can still influence our dimension, but almost always don’t care to. the Culture is actually considered somewhat tacky by other galactic civilizations for being at a fairly late stage in its development without Subliming. they know how to do it, so chances are they just aren’t bored enough yet.

yud omits this (probably, I’m not gonna go back and check), but anyone who chooses an infinite existence at the cost of their own sanity is considered a fucking weirdo who should be sneered at. the Culture isn’t gonna end your existence (they don’t do murder, and there’s a possibly even bigger stigma against forcibly altering a sentient being’s mind) but they’re also not gonna actively enable you to self-harm.
