...that kinos will not be made anymore because the average IQ of the population will become so low that they will only want to consume Bollywood tier slop?

And it's going to be a recursive effect, the more slop they consume the lower IQ they will become, and since all the media will cater to their low IQ slop craving sensibility, their low IQ will constantly be validated. And any time you criticize them, they will call you "against the working class" or "against the 'normal people'" or an "academic" or something like that. They will constantly play the victim and you can never criticize them. And they will vote for dumb leaders who will enact policies to further reduce the IQ by taking away funds from education etc.
