It seems that no matter what technical progress we make, someone is going to complain that they like the old way better. And they will of course have extensive “scientific” reasons for their preferences, since appearing scientific is how we increase or persuasive effect. Now it may be that there is some small but measurable effect on people (I haven’t noticed it after extensive LED exposure). But if you want to figure out why so many people’s health is totally ruined look at industrial agriculture and big chem. You literally eat that stuff all day long. So what is more likely to be messing you up – some photons on your retina on a less preferred wavelength, or the cocktail of pesticides, antibiotics, flame retardants, off-gassing plastics, etc that you ingest all day long just by participating in modern civilization?
