Human condition writing like philosophy and religion formation peaked about two millennia ago. Once its figured out, there isn't too much new to say, unlike, say, technology or fashion. You can write a popularization or translation once in awhile. An eternity of profitable textbooks are possible, just like mathematics.
If you'd like a vision into what Moores Law or computer science will look like in 2000 years, you could do worse than comparing to the humanities peaking 2000 years ago. In 2000 years there will be academic disciples reading Knuth and the lambda-ites will continually be having "revival" journalist articles written about them every couple years and their heretical un-natural love of parenthesis.
It would be interesting to argue that position against something like geometry where at the entry level there really isn't much new beyond Euclid however at the higher end there has been progress and at the low end modern textbooks don't resemble "The Elements" very closely even if conceptually there is nothing new.
Strong fact based arguments could be made either way. Halting-problem-like, the most effective way to figure it out will probably be to wait 2000 years and see what happens.
