Reminds me of some weirdo bodybuilder on YouTube who advised a viewer suffering from depression to become a mercenary in Africa to cure it

Gradient descent with a good line search (Wolfe conditions) applies to the multidimensional case should converge to min, but it might take you thousands of iterations. Newton’s method or something might take <50.
But machine learning practitioners will know why gradient algorithms are often preferred despite this
These guys built a more biologically plausible model and got it to do very simple tasks

Don’t know if their lab has had more success or not on practical tasks but that’s not really the point I guess
Frankly, I think a lot of managers in some places (maybe places you wouldn’t like to work) would care more about their employee being good at inflating their accomplishments and engaging in low-scale office warfare with people outside the group than having really good technical skills.
At one of my employers I was hired at a probably bad time in my life where I was quite unskilled technically (spend a whole day or something to write a fairly simply SQL query), but I would start small office fights (and contribute to office fights of my manager) over any perceived slight, and always view anything my team, me, or my manager did as delusionally impactful and important and loudly proclaim it to everyone around. They bent over backwards to keep me on board. But the technical level of this group was extremely low, so if this was in a group where someone else could verify that I wasn’t that good it may have played out in a more normal manner.
As I invested a lot in my technical skills and got a lot better/more efficient at my actual work (while caring less about fighting office people about their choice of wording in an email or something) they all began to hate me, with my manager wondering aloud to me why I had become so much worse of an employee after a great start.
