Echoing Forrest, thanks Hal. That was the most focused argument I=92ve
seen yet against some elements of the Hedonistic Imperative that I=92ve
always found very disconcerting.

(The concerns I=92m talking about were also briefly mentioned in )

But then Forrest Bishop wrote:

numbers work) then it suggests to me that the loss of information

insignificant compared to the amount which will be created and

If the time from now to =91The Eschaton=92 is longer than the time since
the beginning of the universe, or if the universe continues
indefinitely, then, sure, the loss of past =91information=92 will seem
"insignificant compared to" the future =91information=92 to be created.=20
But, as you also point out, look how much could flow from "that first
step of destruction". Life could probably recover but I can only echo
Forrest in thinking that it could never be the same. Brute-force
resurrection only seems possible within an Omega-Point situation of
infinite computational resources, if then.=20

Hal also asks:
< Well, that's my question. When would it [past knowledge] be useful?
How would it be useful? Give me some ideas of what you're thinking
of, here. My conception is that the Power is so, well, Powerful that
I can't see how the historical knowledge would matter. But most other
people seem to disagree, so I'd appreciate some examples.>

To me it's debatable just how much 'power' these future Powers can
have. But aside from that, it's not so much going back and
reaccessing past information, it's what would be lost in the future in
terms of diversity if certain elements of the past or present are
*expunged* from continuing into the future. (Not a very good
'example', hopefully someone else will be more clever - which is why I
hope for a diverse future and not some monistic Power calling all the
shots :-)
