All I can say is I am glad I embraced my lighting interest and collected what I could afford to, years ago (though I wish I had started doing it when I was younger). Even more than that, getting together with other collectors & enthusiasts and cruising around looking at the remaining incandescent, mercury, fluorescent and other interesting old lighting was wonderful and memorable and I am very happy I had the opportunity to see and photograph many installations that are no longer there. Driving down a main thoroughfare lit exclusively by clear mercury lamps is a magical experience the younger generations will never experience.
I never expected the LED takeover to be quite this fast. It was bad enough with the start of bulb bans and mercury, incandescent and T12 fluorescents going away, but LED has obliterated all other types of light sources and the conversion is happening as frighteningly fast as climate change. I no longer have an interest to go out and search for old lights, or go to the store to buy lamps. I basically consider myself out of the hobby other than maintaining the fixtures that I have at home, and posting old photos. My goal now is just to keep my home lighting working and avoiding converting ANY HID or fluorescent fixtures to LED (I do use LEDs in battery-powered and low-lumen lights or for special effects).
Aside from that I still like designing with light and am happy to help people improve or maintain their lighting of any type, but I get no joy looking at streetlights turning on, or identifying roadway fixtures or trying to see what kind of LED tubes or corn cobs are retrofitted into a fixture now. I could care less. The LED takeover took away my joy and I'm very glad I didn't decide to work in the lighting industry as it would make me too sad now. Though the state of the planet now and the greed and the stupidity of humans also make me sad. The good news is I am not tempted to walk into the lighting department at Home Depot any more than I want to walk into the plumbing or lumber department.
Gee, did you read my mind?
Lighting is pretty much what made me want to become an electrician ten years ago. Various factors could explain why I moved on to other stuff later, but maybe I also had the intuition lighting would soon get super boring, who knows!
And now I focus on what I have power over. It's still possible to find NOS (or just plain old used) equipment laying around, so I can design and maintain my own lighting, especially with incandescent lamps. Needless to say I've been using exclusively incandescent Xmas lights for several years now! Those transparent-coloured lamps are just so pretty!
