LEV probably within 20 years in the lab plus another 5 years or so for widespread deployment.

Actual biological immortality, maybe add another 10 - 15 years, although it's an open question whether mind uploading will arrive first and make the biotech approach obsolete.

Surely we'd need to understand the basis of consciousness first. What is the principle construct of matter that forms consciousness? At what point does consciousness arise from organisation of matter? What are the mechanisms involved etc?

You mean for mind uploading? Honestly, probably not. I doubt we'll have entirely solved the HPOC by the time we figure out mind uploading technology.

We will figure out what sorts of algorithms generate consciousness, even if we don't entirely understand why. That will probably be achieved before we master mind uploading, or at least not long after.

Generate actual consciousness or an illusion of consciousness? The issue is the definition of consciousness itself and there are multiple philosophical definitions and thoughts on consciousness. Even if a machine appears to have conscious thought it doesn't mean that machine is actually conscious. I for example believe I'm conscious because I have awareness of my surroundings and inner reflection of my being. Of course that is my own belief in my experience. However a person could believe they are the only conscious being in the Universe because they only experience their own Intrinsic consciousness, of which they assume is the same as other humans.

So whether a machine has actual consciousness in the way humans experience consciousness there doesn't exist a test. We can perform experiments/tests to see if the machine is representing consciousness in the same way we do but that doesn't mean the machine is conscious.

The real thing, of course. Fakes only take you so far.

It can strongly suggest so, especially if we combine it with a robust algorithmic theory of consciousness.

Presumably none of us will ever be 100% certain that we're not the only thinking being in existence, but that's fine, we get plenty of other things done with less than 100% certainty.
