An interesting discussion, at least for a futurist / SciFi writer.

If you know someone is x years old then you can know (generally) that they will almost certainly live y more years and will be almost certainly dead in z years.

However if you know a technology (defined almost as you like but embodying knowledge) is x years old then you can (generally) expect it to last at least x more years.

So as x gets larger Tlife gets longer but Plife stays the same…so aging, that is the rough measure of, age/life, is opposite for tech vs us biotypes… An interesting idea to roll into a story sometime.
