I had an original 2013 Chromecast plugged into my TV for ten years. It did its job admirably, until it started becoming more and more unstable and began rebooting randomly with each new OS version that Google pushed. I finally replaced it about a month ago with an onn streaming box from Walmart for about 20 bucks--less than I paid for the original Chromecast a decade ago: https://www.walmart.com/ip/onn-Google-TV-4K-S…
I'd really like to stop updates when I get something that works, but alas, Google "cares about my security".
