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?
Hi-fi stereo systems with amplifiers, speakers and cables.
I could be wrong, but I think that old stereo systems generally have way better sound quality than Bluetooth systems, soundbars and the like. Physical media such as CDs or even Flac files (etc.) are of course impractical compared to streaming, but the audio quality is much higher.
However, since you can also stream audio without any problems, I would recommend every music fan to buy a used stereo system with high-quality speakers from the 2000s or even from the late 90s - in my opinion, excellent audio quality at a low price.
