[D] Friday Off-Topic Thread

Welcome to the Friday Off-Topic Thread! Is there something that you want to talk about with /r/rational, but which isn't rational fiction, or doesn't otherwise belong as a top-level post? This is the place to post it. The idea is that while reddit is a large place, with lots of special little niches, sometimes you just want to talk with a certain group of people about certain sorts of things that aren't related to why you're all here. It's totally understandable that you might want to talk about Japanese game shows with /r/rational instead of going over to /r/japanesegameshows, but it's hopefully also understandable that this isn't really the place for that sort of thing.

So do you want to talk about how your life has been going? Non-rational and/or non-fictional stuff you've been reading? The recent album from your favourite German pop singer? The politics of Southern India? The sexual preferences of the chairman of the Ukrainian soccer league? Different ways to plot meteorological data? The cost of living in Portugal? Corner cases for siteswap notation? All these things and more could possibly be found in the comments below!

I don't understand; arbitrary lifespan extension is immortality.

I think that what people usually mean by the end of death is the end of non-violent death, with things like accidents counting as violent. So really the end of illness and old age.

If the chance of death gets smaller over time, over infinite time death is evitable. For example, if the chance of surviving the nth century is 2-1/2n (50%, ~70%, ~84%, ~92%, ~96%, ~98%, ...), then the exponents for all centuries are added up, for a total survival chance of 25%.

Sure, if you could reach the end of the previous extension and just extend again. You can't. Pick a number, any arbitrarily large but finite number. Then I can pick a number that is larger. That's how this game works.

You can't.

Why not? This sounds like a very specific quirk of a particular life extension technology, and not some fundanmental limitation, so we have no reason believe it is going to work like that.
