When non-tech people ask me whether they should invest in quantum computing I tell them nobody alive today will live to see a return on their investment in quantum computing. Not because it's impossible but because the engineering challenges to make it truly useful outside the laboratory are too great, despite what the press releases would have you believe. I tell them the same thing about fusion energy.
