It would be interesting to see some actual calculations around this. It would have to take into account, for example, that we can do (some arbitrarily huge number) more calculations with N grams of rare materials than we could back in the day. If that trend continues for at least another while, investing in a 50-year computer is basically saying we have absolutely no need for that extra computing power.
