The thing is, those "famous comments" are a form of survivorship bias.

"People are saying Google Glass was silly, sounds like a dropbox comment, surely it'll become the next big thing"

"People are saying the Humane AI Pin is useless, you can just use your phone, sounds like the dropbox comment lol"

"People criticized ScamCoin5000 saying 'just do a regular ponzi scheme with cash lol', people also said 'just use ftp' about dropbox, so surely ScamCoin5000 will be the biggest thing since sliced bread"

It's a frustrating thought-terminating cliché, and I'm really tired of hearing it at this point. "The internet started small, so that means the crypto/our ICO/NFTs/metaverse/AI is also just at the beginning but will become huge", uh huh, sure.

To quote Carl Sagan, on an older form of this phenomenon: “But the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown.”

Though tbh I might take Bozo over Columbus.
