The same thing happened in the pro synth world.
When the DX7 came out in 1983, people were wowed by the decent piano sound, for example, which was something analog synths never did well. There were lots of sounds like that - bells, xylophone etc.
Then sample based keyboards started to get more affordable, and RAM and ROM got cheaper.
Eventually in 1988 came the Korg M1. Megabytes of samples in ROM let it do a perfect piano sound, along with a horde of other great sounds, natural and unnatural.
The M1 became the best-selling synth in history and the world's fascination with FM finally faded.
