> There is no textbook that explains quantum mechanics for smart 15 year olds
That's because you need a level of mathematical maturity to understand modern physics and QM that 99% of 15 years old haven't done. Maybe you were trying to prove a point but that's a bad example, pedagogically speaking. Point being by the time you're ready to meaninfully learn QM you don't need to dumb it down to ELI15.
Anything else is pop-science. IF you really want to learn this stuff you can start here: https://goodtheorist.science/. Note the first steps are learn enough math so you can 'speak the language of physics'.

Have you done a study like this before?, I'm not sure if you know but:
Again an LLM is not going to be able to know this because the data comes from private primary research, which you would either gather yourself, sift through trade reports, or engage a consulting or market research firm to go find out.
This is firmly beyond current LLM's ability to synthesize, since the data is literally:
a) private, paywalled, expensive to procure,
b) extremely temporal, in that the market landscape changes year to year or even faster.
You would start somewhere like https://www.bain.com/insights/industry-insights/healthcare-i... and then need to go buy things like https://www.premiummarketinsights.com/reports-tip/north-amer...
and then trawl https://www.linkedin.com/pulse/global-respiratory-care-devic... for experts who you might need to pay to interview.
Sure some of the companies are publicly traded, in which case you can go look at 10k forms etc., but the sources of knowledge are private, expensive, and rapidly changing for that kind of question.
