Haven't heard of optogenetics in a while. I could never decide if it was actually useful for either basic science or medicine or a toy.

Looking at the basic science results I could not decide if they were bringing in really novel understanding or basically repeating a lot of the old electrical stimulation results.

I do remember a staggering amount of money was pumped into the field and it was super trendy in the 2010s.
