I used to think this same thing but I went down a rabbit hole a few months ago listening to people very critical of string theory like angela collier, sabbine, eric weinstein, peter woit and some others on youtube. Yeah they all have their own quirks but after listening to their take on the history of string theory the common things are it hasn't produced anything but the major proponents of it always talk like it has and in some cases outright lie about things that it has contributed.

I really like listening to brian greene and sean carroll but now when I listen to them, particularly in recent videos, it feels like there is much less substance to what they're actually saying string theory has done.

But who knows! Maybe I'll learn something new and completely flip my world view again, I'm not a physicist by any stretch so have to rely on listening to experts :)
