When you connect a new device to a ‘smart’ tv, you must pay homage to the manufacturer with a ritualistic dance. Plugging and unplugging the device. Turning them on and off in the correct sequence like entering a konami code.
Every time you want to switch devices, the tv must scan for them. And god forbid you lose power, or unplug something. You are granted the delight experience of doing it all over again.
I have fond memories of the days of just plugging something in, and pressing the input button. Instant gratification. It was a simpler time.
What is some other tech that used to be better?
XML is meant for you to create & embed entire namespaced specification schemas that don’t have very strict limitations. JSON schemas are more ad-hoc than a built in since it isn’t a part of the spec or namespaced & IIRC Matrix uses events all stringly-typed by a message name instead of the XMPP approach which assumes already the message body can/will contain arbitrary data according to a XEP or other spec. I’m non as knowledgeable on the subject as I would like to be tho…
