An important number of those remarks were based on a snapshot of the state of the technology: a fault in not seeing the potential evolution.

Examples of people who could not see non (in some way) dead-ends do not cancel examples of people who correctly saw dead-ends. The lists may even overlap ("if it remains that way it's a dead-end").

In fairness to Irving Fisher: if you bought into the market at its peak in 1929, you wouldn't recover your original investment until about 1960.

I am just wondering did you have this all somehow saved up or did you pull it out of somewhere? Amazing list of things. Thank You.

Gosh no. I knew most of that list but I'll be honest and tell you that I used ChatGPT to come up with it. it's a collection of quotes to begin with so I think that's okay. I'm not passing off someone else's writing as my own, I'm explicitly quoting them.

I'm pretty sure that Lord Kelvin was also in the cohort of fools that bullied Boltzmann to his suicide.

*formerly great minds.

In many cases the folks in question were waaaaay past their best days.

I doubt that list is as long as the great minds that glommed onto a new tech that turned out to be a dud, but I could be wrong. It's an interesting question, but each tech needs to be evaluated separately.
