<pre>suppose we had a sim which could run a our speed, at one human

think so. But... perhaps not. Perhaps 50 million years of one human

Sufficient for what, spike?<br>
<br>
We can't assume that aliens would have the same psychology as humans
("The thing about aliens is, they're alien"), and we can't assume
that uploaded humans would remain the same, mentally, as biological
humans. In fact I think it would be extremely surprising if they
did. So what might be 'sufficient' for a biological human (or alien)
almost certainly wouldn't remain the same for an upload.<br>
<br>
To me, at least, the whole point of uploading is to break free of
the constraints of biological life, both physical and mental. For an
upload that managed to maintain the same psychology as it's original
biological form, I wouldn't be surprised if a few thousand years
would be 'sufficient', and a few million might be unbearable. But I
think it's extremely unlikely that an upload would remain the same,
mentally.<br>
<br>
I don't think we can really even guess what 'sufficient' would mean
to an upload, alien or human, in terms of subjective lifespan.<br>
