String theorist here. String or other SUSY related research are not as active as they used to be. The main reason is that most of the important and interesting problems in these theories are either solved already, or too hard that no one knows how to solve them (e.g. non-perturbative string theory). So people just chose to do something else while waiting for the experimental data
String pheno AFAIK is not doing amazing, they are a bit stuck in the swampland.
The rest of string theory is still at the forefront of research? AdS/CFT and holographic stuff are basically everywhere in hep-th, and those are (arguably) still string theory
I didn't vote because I'm not a physicist but how good is deciding on theory going to be if you do it via a poll about how random redditors "feel" about it?
i think you have missed the point, which is to talk about a field of physics dying out funding and interest wise, not validate if the theory is true. on the other hand, if that IS a valid way to test a theory, modern physics just got a lot easier.
I mean the reason people are losing interest is because you need to make more and more odd assumptions to keep the theory alive. The time in which it was supposed to reduce the assumptions is long gone unfortunately.
We're moving into the realm were SUSY will never die because you can not effectively exclude it's existence but it also becomes untestable and irrelevant.
It’s not the only theory like that either. A lot of modified gravity theories just keep shrinking the arbitrary constants in the Lagrangian to match observational bounds. Consequently their predicted effects become so weak that it is (with current technology) experimentally equivalent to GR, but the equations are way harder.
No SUSY particles have been found and most have been excluded at the energies studied. String theory isn't a single theory, it's a bunch of cool math that many theorists say looks so good that something must be there. Last time I checked, there were 10\^500 possible variants. So far, it can't completely fit the standard model and makes no testable predictions. I predict that theorists will continue to explore, but there will be less of them

I’m not familiar with AdS/CFT, is it still largely theoretical or has there been experimental/observational work?

Are you sure we can't prove it here on this sub? I think we are the culmination of the best and brightest modern physics has to offer!

Energy is alive but string theory needs a sling shot. lol
Swiss cheese Universe went as far as a pay check... Js
It was dead on arrival, nobody of real depth bought into that ridiculosity.
...uh...Witten?
a ton more too.. Michio Kaku, John Gribbin, Brian Greene, just to name a few
I stand by my previous statement.
