Re:What makes quantum computing so hard to explain?

Shipping your quantum algorithm requires access to a limited number of very expensive quantum computers that, for all intents and purposes, are not actually available.
A classical algorithm can be run immediately on commodity hardware tomorrow. And, most of the time, novel quantum algorithms actually can be matched or beaten classically.
Given that it makes sense to spend a small fraction of the cost of the needed quantum computer looking for the classical alternative. Preferably before you start investing in building the quantum computer.
