Hi John, I wondered why you hadn't been heard from.

Good point. To some extent it's just a matter of semantics. I should
clarify one thing: I don't think the whole process will be finished within
a half-century. It will be well underway by 2050, but it will take a lot
longer to reach a conclusion. Nevertheless I grant you that on a
geological time scale, a major extinction event and the emergence of a new
phylum (or a new kingdom) could be considered a discontinuity. However,
what appears from a distance to be discontinuous may appear differently

In the last 200 years, we have already seen the potential elimination of death, in the sense that it is no longer necessary for most people to die young. This has certainly had a dramatic effect on human society, but the change has taken place within an unchanging framework. In the coming century we will see a further development along the same lines -- it will no longer be necessary for some people to die at all, at any age. This too may have dramatic effects on society, or it may not, but in any case this too will take place within an unchanging framework.
Organisms come and go. On a longer time scale, species come and go. This will continue. As hard life emerges from soft life, organisms will still eat each other, and on a longer time scale species will still come into existence and eventually become extinct. (Think of corporations, which could be considered the prototype of hard life: corporations come and go. Industries come and go.) Biological changes, like other changes, will take place within an unchanging framework.
Since my original "hard life" post was on the old list (not in the archives), maybe I should restate what hard life is. It is possible to design cells with the following properties:
This is what I call "hard life." Hard cells will not completely replace soft cells (i.e. natural cells), but over time they will relegate soft cells to a minor position in the ecosystem, like anaerobic bacteria. That's the extinction event I am speaking of. I have no idea how long it will take, or how it will play out, in detail.
