Hello, SFIA audio listeners. In this month's Nebula exclusive, big alien theory,

we're asking the reason alien civilizations might be rare is because most aliens are huge.

Welcome to another episode of Science and Futurism with Isaac Arthur, and I'm your aforementioned

host, Isaac Arthur. Today I'll be going through a lot of the potential ethical conundrums people raised about

life extension and adding some lesser known ones too, as we consider if this is really

a technological path we should be pursuing.

We'll be trying to treat the subject neutrally, and we're also picking sub-topics in part

by the frequency I've heard

them rather than their specific logical or scientific validity, but I feel they should

be treated respectfully nonetheless.

Many of the arguments apply to other areas of technology as well.

I should also say from the outset that I'm a bit biased on the topic.

After almost a decade of doing a show on science and futurism, one of the most common

questions I get asked is what technology we discuss on this show that I would most like

to see invented in my own lifetime, and the answer is life extension technology.

And that answer is a bit tongue-in-cheek, but also sincere.
