Never going to happen. We don't have the technology, we're not going to get the technology, and nobody benefits by having wealthy people around forever. Your body parts will eventually wear out regardless of what you try to do to mitigate the situation, and everybody will get terminal cancer sooner or later regardless of anything else. And even if THAT doesn't get you, an accident eventually will. Doesn't matter if it's a car wreck, a plane crash, someone coughing on you at the wrong moment, or you sneezing and bursting a blood vessel in your head.

The big assumption in this counterargument is that we stay biological forever. I see biological "immortality" (anti-aging) as a temporary stopgap while we develop gradual replacement and migrate to a synthetic/digital consciousness, hosted on nodes distributed throughout Earth orbit or beyond for fault tolerance and availability.

I'd be shocked if this didn't happen in the next thousand years.

Needing air/water everywhere we go is incredibly limiting as well.

You won't "migrate", it will just be a copy of you. Your conscious perspective will not transfer to the copy of you. You will still be bound to the original, even if a simulacrum of your mind is created.

You can "migrate" with a technique such as gradual replacement, which in a simplified form replaces one physical neuron at a time with an uplink to a virtual neuron, and waits for your thoughts to equalize. Realistically you'd do clusters of neurons.

And how do you plan to deal with the latency of connecting the neurons of your brain to a remote virtual uplink? The speed of light limits the size of a virtual brain that is able to function in the same manner as a biological one. The truth is our understanding of consciousness and its neurological foundation is nowhere close to the level that would allow us to recreate it artificially. We don't even know how it works normally. It will not happen in your lifetime and you are going to die like the rest of us, and very likely this will not change even in the next thousand years.

And then when the hormones are also gone, you won't be you. You won't even be a copy. You'll be a husk pretending to be a person long after the actual person is long gone. You'll be a talking wikipedia article with no ability to anything but regurgitate some of what you already knew, and the vast majority of these things will be of no consequence or use to anyone. We will never need immortality badly enough to spend the kind of resources to come close to achieving it.
