Idk, if you're doing the same thing after your training that you were doing before, you either didn't need training or you weren't successfully trained.
It's an idiom, it's not meant to be a clinical diagnosis. Like, yeah if you're psychiatrist says it to you qnd tries to have you institutionalized, that's obviously a problem. But I highly doubt that's ever happened, certainly not in the modern age.
Ultimately, it's actually the same exact idea as "Those who ignore history are doomed to repeat it," but in less politically correct terms.
think the meme has some grounds for truth. of course it was designed to be a dramatic speech for a scary character but it has some grounds to it: this may not be the truth but its how it feels. By doing the same thing over and over again and seeing no chance you go insane, and as such it feels like doing so is asking for insanity, thus the characters speech!
For the training, I'd argue that you're not trying to get different results.
Each time, the result is minor growth in whatever your goal is, be it strength, muscle mass, or endurance, etc.
Doing the same thing over and over with an expectation to see differing results is also science.
But also if you keep running the compiler without changing any of the code hoping for the errors to be magically gone, you are insane. So there's the same logic being applied to insanity in computer science
I don't quite understand the rage against this guy, imo he's one of the more likeable and interesting billionaires in the world. At least he has visions and wants to change the world for the better, something you cannot say about Jeff Bezos or Mark Zuckerberg etc.
He suggested that Ukraine should surrender to Russia and give up their Land. His own daughter hates him so much that she expressed in court that she doesn't even want to inherit his money or be related to him in any shape or way. He cancelled the Tesla order of a blogger after the blogger said he was disappointed that Elon musk made a bunch of people wait for multiple hours without communicating anything. He is known as a bad boss that overworks his workers and pays then poorly. He has shown himself to be transphobic, ableistic, racist, ageist, hypocritical and a liar
I like that guy. Very likeable.
Reasons:
He is a petty person; he called one of the divers saving Thai children a pedo, tried to get a lawyer fired for successfully suing him, is suing the firm which forced him to buy Twitter
He fights unionization while tesla has safety and racism issues, and just look at spaceX on glassdoor
His securities fraud, plus dogecoin pump and dump
He dislikes mass-transit and blocks actually helpful transit ideas with Boring & Hyperloop
And ofc his management of Twitter leaves much to be desired
He is an alt-right douche and it escapes me how him constantly being purposely antagonistic for fun lends to being "likeable". The abhorrent political views would be enough, but there's a lot more.
