Also, TVs went from dumb to smart, so empirically,
sufficient buyers voted for smart even when they
had an option for dumb
This is one of those areas where consumerism/capitalism trips over itself and leads to sub-optimal outcomes.
The implicit assumption here is that this must be what consumers want, because it's what they "voted" for.
But voting (whether democratic elections, or just free-market consumer spending choices) only leads to optimal outcomes when the "voters" are sufficently knowledgeable in terms of both general domain knowledge and the choices themselves.
For all but the simplest choices (say, a choice between a bucket with a hole in the bottom and a bucket without a hole in the bottom) this is difficult.
There's no reasonable way for consumers to know how shitty the inbuilt OS/apps of a "smart TV" will become over time, or what onerous software updates the manufacturer will pump out, etc. A lot of this stuff is difficult or impossible to know even for savvy, educated people looking for a TV.
I wonder what sort of reaction you have when a successful, legally approved medicine turns out to cause death or injury in the long run, or merely proves to be ineffective. Or when a specific model of car develops problems after a couple of years.
Do you say, "well... this is clearly what consumers voted for?"
