During a report on his death I heard this quote attributed to Stephen Hawking. I can’t find an attribution for Hawking, though I did find a Quote Investigator article discussing the quote’s origin, attributing it to historian Daniel Boorstin with earlier influences saying basically the same thing. No matter who wrote/said it I really like the point that is being made.
