Personally I don't see the death of cable, at least not in the way it appears you do.
Eventually I suspect that there will be replacement for cable, a way to get all the streaming services you want bundle together for one price. And the reason why I think this is because not everyone wants to pay for individual streaming services. As it is now just here in the US we have 3 main streaming providers with Netflix, D+/Hulu, and Amazon, with several more bringing up the rear with AppleTV+, Paramount+, Peacock, and HBOMax. And that is not to mention all the numerous smaller ones and all the ones outside the US. Add just the 3 main providers and 1 of the smaller ones together and you are effectively paying the same amount as a basic cable package. Meaning all those cord cutters that were tired of paying the cable prices and switched to streaming are basically right back where they were before. And to add insult to injury STILL getting content you may not want, which is part of the reason for the switch in the first place. Most people I know have at least the 3 main providers, so in reality most aren't saving what they expected by dumping cable. And with prices on the rise it'll just get worse.
The solution I see in the future is a service provider that will bundle all the different streaming services you want together for one single price offered in a single interface, effectively a replacement for the traditional cable provider. Heck it may end up being one of the existing cable providers that offers this service, they may even be trying to work on this now for all we know.
So no I don't see the death of cable coming, at least not a complete death of cable, but rather a transition to a new type of cable provider for streaming services.
