Yes. But there is another problem. When a super-civilization goes to sleep, for the Universe to cool some more, it has to establish some alarm clock mechanism to wake them up after some time. Which needs some energy. If they circuit their alarm clock to a thermometer to wake them up when it will be cool enough, is that energy free? I don’t think so.
Well, I don’t believe it’s possible to postpone the end of all calculations indefinitely, but I still find this Dyson text fascinating and very relevant.
I believe Dyson is saying there could indeed by an infinite amount. Here is a wikipedia article about it https://en.wikipedia.org/wiki/Dyson%27s_eternal_intelligence and the article itself http://www.aleph.se/Trans/Global/Omega/dyson.txt
