Midjourney's Spa, or when sci-fi tries to become mundane

Midjourney has just announced their jump from being just the "makes funny images" AI company to being the "revolutionises diagnostics and human medicine forever" AI company, as a side gig. Here's the post.Basically, they've announced the creation of a highly advanced full-body ultrasound scanner beyond anything that's been done until now. The description of the process sounds straight out of a science fiction novel:It starts by stepping into a shallow pool of golden light. You then begin to descend into the water. Your body passes through a ring of underwater sensors, each acting like a dolphin, using its echolocation. The sensors send ultrasonic sound waves through your body from every angle. With enough waves, and enough angles, we form an image of what's happening inside your body.This is meant to make something equivalent to MRI into a cheap, trivial occurrence. You just go and pop in for your daily full-body scan. The one day it happens to find a cancer, no big deal - it's going to be early enough that you can just get it removed swiftly and with little consequence. In fact, you might eventually go to the spa just for fun and relaxation - the scan purely a nice side benefit:Our spa will have hot tubs, saunas, cold plunges, and cozy rooms with pools of golden light which softly scan your body.It should be a place you love going, whether it's by yourself, or with friends. It should be available 24/7. The scans are a side-effect. You barely think of them when going to the spa. But suddenly, you have a huge library of data about your health.That sounds... kinda incredibly awesome? I get regular cheap checkups, and a revived public bath culture? I mean, don't mind if I do.But then the "too good to be true" bug bites.Space truckin'I feel like if there's one lesson to take from the last few years, it's that when things that were science fiction turn into reality, they have a way of becoming way more controversial and less cool than they looked in the shows and movies
