It sounds possible. However, before even the first people will get it, there should be some progress with animals, and right now there is nothing. So I would bet it is not going to happen in let's say next 5 years. (Well, unless we suddenly get a radical progress in creating a superAI that will do it for us, but this is the huge another question on its own). I would say, I wanted first to think about the very near future, without a huge technological breakthrough. Of course, the immortality and superAI are far more important than anything I mentioned in the original post. However, I think there is a non-negligible likelihood for something from the original post to happen very soon (maybe even this year), while the likelihood of the immortality before the end of this year seems quite negligible.
