But I’m not sure how many real-world problems there are of high economic value which can soak up a year of serial processing.
Think of any real-world problem that takes one day on modern hardware. When computers were 365 times slower (that is, 12 - 13 years ago), it would have taken one year to solve such problems.
Don't you think there is any real-world problem that would benefit from 365x faster hardware, even if you can interact with it only once a day?
(Even if individual tasks take less than one year to complete, you can pool several of them and run them serially on the 365x computer)
Most of the examples people would come up with of extremely compute-intensive tasks are parallel algorithms, and those would be cheaper to run in the real-world on server farms which do not need self-contained powersources fitting in an HTC or similar special setups or attendants paid handsomely to be willing to spend a year isolated in the prison of HTC. There's simply no reason to take a highly parallel task and run it in an HTC when you can get the same result at less cost and less latency by running it on a perfectly normal server farm or cloud computi...
