That's because they're not really that hard. Compilers are essentially pure functions, encryption is as well. State is another beast entirely. If I had to put on my innovator cap and do a relatively weakly informed guess, I'd say its because querying capabilities and reliable storage are still too conflated. If we focused on reliable storage that only has great replication support to other querying systems, the problem might get easier.
