for instance, the movie (and tv) business more readily lends itself to a repetitive process constrained on storytelling, which is more focused, on a macro scale, than tech. it would be akin to tech companies settling on only building web businesses over and over again, albeit with different twists. the video game sector has possibly hit that kind of stride.
i don't know that this affects their ability to succeed though, well-funded or not.
Streaming video for example has more or less stopped producing viable venture startups on the B2C side. Successful new ventures in streaming, the ones who will actually make money, are folks like Disney and Warner with IP. Their business advantage is horizontal integration, rent seeking for content with killer margins over company-controlled pipes. Disney Plus, HBO Max apps have zero notable tech innovations. The only criteria to the consumer is that the content is exclusive and the app stays in the background and doesn't fail. OTT video, as a vertical for consumer innovation, is over.
Same goes for SaaS, ecommerce, social networks, gaming, music, news etc. Maybe we'll get some standout disruptions from time to time as hardware evolves. But the tech is all about plumbing from here on out..
