Not I.  If we get the whole uploading thing going, so many of these kinds of
problems may become irrelevant.  We perhaps could downscale the clock speed
so it is working only one trillionth the speed it is capable of running, so
the 4 million year trip would go by in an acceptable perceived 4 years?  Or
go down to a quadrillionth the top speed, so the 4 million year trip would
feel like a trip from Australia to Texas on one of our Booeings?

Ja, I have more calculation to do on that.
