I absolutely hate "smart" TVs! You can't even buy a quality "dumb" panel anymore. I can't convince the rest of my family and friends that the only things those smarts bring are built-in obsolescence, ads, and privacy issues.
I make it a point to NEVER connect my new 2022 LG C2 to the Internet, as any possible improvements from firmware updates will be overshadowed by garbage like ads in the UI, removal of existing features (warning: reddit link), privacy violations, possible attack vectors, non-existent security, and constant data breaches of the manufacturers that threaten to expose every bit of personal data that they suck up. Not to mention increased sluggishness after tons of unwanted "improvements" are stuffed into it over the years, as the chipset ages and can no longer cope.
I'd much rather spend a tenth of the price of my TV on a streaming box (Roku, Shield TV, etc.) and replace those after similar things happen to them in a few years. For example, the display of my OG 32-inch Sony Google TV from 2010 ($500) still works fine, but the OS has long been abandoned by both Sony and Google, and since 2015-16 even the basic things like YouTube and Chrome apps don't work anymore. Thank goodness I can set the HDMI port as default start-up, so I don't ever need to see the TV's native UI, and a new Roku Streaming Stick ($45) does just fine on this 720p panel. Plus, I'm not locked into the Roku ecosystem. If they begin (continue?) enshitifying their products, there are tons of other options available at similar price.
Most people don't replace their TVs every couple of years. Hell, my decade old 60-inch Sharp Aquos 1080p LCD TV that I bought for $2200 back in 2011 still works fine, and I only had to replace the streamer that's been driving it twice during all this time. Sony Google TV Box -> Nvidia Shield TV 2015 -> Nvidia Shield TV 2019. I plan to keep it in my basement until it dies completely before replacing it. The Shield TV goes to the LG C2 so that I never have to see LG's craptastic UI.
Sorry, just felt the need to vent. Would be very interested in reading community's opinions on this topic.
As the owner of original $500 Sony NSX-32GT1 TV from 2010, I can tell you exactly how different it is. Its UI wasn't exactly a snappy experience to begin with, but it's gotten even more sluggish over the years until everything stopped working due to being EOL. The OS on it has been unsupported since around 2016, so it's stuck on ancient Android TV version. Most apps (even built-in ones like YouTube) stopped working a few year later, and cannot be updated.
Sure, a $50 Chromecast will eventually suffer from the same problems, but I can replace it 10 times for the same amount of money while keeping my TV because its 32-inch 720p panel still displays content just fine.
While true, the context of this discussion was mostly about privacy rather than functionality. Builtin Chromcast vs external changes nothing on that front. There is also nothing that would prevent you from plugging in that fancy new external Chromecast to the old Sony and getting new functionality from it if the display is still to your liking.
