I think some must genuinely be lying. I find it hard to believe they can be that dumb.
Never underestimate the utter stupidity of the highly credentialized. It usually people from a purely academic background with no real world application of the science experience. Where their nice little equations and graphs completely fall part when they hit the complexity and messiness of the real world. In their papers they can remove all variables that cause problems. Or the stuff they that they dont understand. The real world is not like that.
It happens in all fields, especially those that are supposed to be “applied science”. On more than one occasion I’ve told a prof with a high profile position at a world renowned university that their “great idea”, with almost two decades of published papers behind it, protected with a patent portfolio, raised millions in VC, was not going to work in the real world. The first time it only took them three years to give up and pivot to a completely different product which made the money back. The second time they just ran out of money after 5 years. Neither worked, for very simple real world reasons.
Some guy who ran a fever clinic in the Congo, they know what they are talking about. One of the (tens?) of thousands of immunology PhD drones, they generally know fuck all about anything that is relevant in the real world or in a clinical setting.
Everyone else is is just conforming to protect their career. Those that dont want to deal with this lying bullshit leave the field. I have worked with many of these people over the years. High tech is full of them.
