Algorithms that don't use quantum computation and plain silicon devices are such a hard hurdle to overcome. I can see a possible future where silicon reaches its limit and maybe then we will be forced to engineer Quantum Computation but even so that is still 90 years of research to get them practical. I found that out when studying Quantum Computation at school.
