Maybe someone will figure things out at the circuit level to get hashes out faster. Or figure out better ROMs (with fewer transistors) to store the 64 32-bit fractional parts of cube roots of primes. Or, someday, someone will come up with the coinotron, which, like a transistor or memristor, would be at the boundary between chemical and electrical engineering, targeted at the bottleneck in the hash.
