ethernet is still with us…
Yes but wireless has not been advancing with backwards compatibility in mind the way Ethernet has due to it's hub like nature. There are wireless device from 10 years ago that you can't use on a modern AP with modern clients, well... not without sacrifices. Plus there's been talks for years about digitalizing wireless communication.
I wouldn't be surprised if before these bulbs die they either becomes uncontrollable or they limit your wifi upgrade options. However, I'll cross that bridge when I get to it, they're still wicked cool.
