They are saying that quantum computing is at the stage that classical computing was at when it still relied on vacuum tubes.

Not that quantum computing is at the same stage as the vacuum tube industry was at at some unspecified time.

It still doesn't wash. Vacuum tube computers were used in WWII to compute artillery tables. That presumably changed (or ended) lives.

I don't think it's a reasonable comparison at all.
