At the surface level, this sounds very similar to Theranos's mission: create a non-invasive testing method that replace traditionally invasive/costly testing methods so successfully that it becomes silly not to gather and sample as much of your health data as possible, in the hopes that more data will eventually translate to better diagnostics.
Of course Theranos failed because they faked the testing tech (and allegedly also the test results) during their failed journey in developing their novel testing tech. Ostensibly, Midjourney is not going down that path, but I wonder why Midjourney thinks its brand is valuable when introducing this product? Because if someone were to accuse Midjourney of being the next Theranos, then Midjourney's fame for a AI-image generation service would slot in perfectly with a grift selling miraculously cheap body imaging tech.
