My impression is that gourmet food has become more interesting as the need for it also to be filling has decreased
Um, gourmet food is almost by definition food that is skilled labor-intensive to produce. For an example of technological superstimulus applied to food think mass-produced food that is sweeter/more satisfying then anything in the ancestral environment, a.k.a., fast/junk food.
See here for the standard examples of superstimuli as applied to food and video games.
I'm not suggesting that gourmet food is a technologically applied superstimulus, I'm suggesting that cheap mass-produced food is a bit like one and that maybe its availability has enabled the flourishing of cuisine-as-quasi-artform.
This is not exactly what you asked for but I think it's still relevant -- it's not so very different from what Viliam suggested could conceivably happen with sexbots. Hence my first paragraph.

Speaking from personal experience, finding the right relationship can be HARD. I recently came across a rational take on finding relationship partners, much of which really resonated with my experiences:

(I'm still working my way through the Sequences, and lw has more than eight thousand articles with "relationship" in them. I'm not promising the linked articles include unique information)
