I, too, am nervous about having anticipated experience as the only criterion for truth and meaning. It seems to me that a statement can get its meaning either from the class of prior actions which make it true or from the class of future observations which its truth makes inevitable.
That seems obviously correct. However, unless you pursue knowledge for its own sake, you should probably not be overly concerned with preserving past truths—unless they are going to impact on future decisions.
Of course, the decisions of a future superintelligence might depend on all kinds of historical minutae that we don’t regard as important. So maybe we should preserve those truths we regard as insignificant to us for it. However, today, probably relatively few are enslaved to future superintelligences—and even then, it isn’t clear that this is what they would want us to do.
