Horse looking at out-of-fashion tech

Personally i like them quite a bit, the small gear steps, i am using the simultaneous shifting like front 1 up, rear 1 down a lot to find myself in the best cadence.

I know people being happy with their switch over to 1x setups, but tbh i don’t see myself doing that at all. I guess 2x, but i wonder how you would get to the small steps, like do you do something like front 1 up, rear 3(?) down, or just get used to the bigger steps?

Do you think 3x drivetrains will ever make a comeback or are they fading out for good?
