All the classical computers on earth running for thousands of years can't do the same calculation that a quantum computer with only 100 error-corrected qubits can do. So from that perspective, QCs will use way less energy for solving the same problem.
He's wrong about "not quite being there yet to building a scalable quantum computer." IonQ's 64 qubit system is a few months away, and it will be many times more powerful than the fastest classical computer in existence today. And IonQ has achieved 99.9% error correction, and they have solved ion-to-ion entanglement, including the coding language to manage it, allowing multiple machines to be run in connection with each other. And their machines require no cooling, fit in a typical server rack, and only require two standard wall sockets to run. Their AQ64 model will be called Tempo. Look it up.
Ask him if it uses less electricity?

Nice palatable introduction to the non intuitive behaviours of quantum systems at the start.

So he is fully correct by saying "not quite there". Anyone saying they are months away from an error corrected QC are selling you fiction.
