Let's create unbreakable DRM

1. All media is encrypted executable code. For example, there are not true videos published, but actual instructions for drawing an image on the screen. Programs are likewise encrypted. Those instructions are encrypted with a streaming cipher public-private key encryption scheme and are decrypted in hardware.
2. The chips in charge of decoding images use the mechanisms of Xerox's self-destructing chips. Any would-be reverse engineer will just end up having his shit blown up.
3. Each chip is etched with a unique number that it's keys are derived from. The media publisher operates a service that the client hardware contacts with it's request, telemetry data, and it's encryption key. The service stores the media in an intermediate form that allows for efficient watermarking and encryption.

Boom, no more piracy or ad blocking ever.

Move everything to the cloud and charge rental subscription fees for the client hardware, which is basically a thin client.

Media and software companies like it because they aren't selling anything, and the product can be revoked at their leisure.
Customers Consumers like it because they're dumbasses and the devices are very shiny. Also very cheap, at only $100 up front and $50/month for the next two years, it's way more cost effective than buying a bunch of $500 laptops that can't even stream the latest hilarious Hollywood comedies because they lack the trusted computing hardware. Additionally, as the cloud gets more powerful, the upgrades are passed along to the consumer for free. You never have to worry about whether the latest Call of Duty, Grand Theft Auto, or Disgaea will run on your system, because the publishers will work with the cloud provider that there is enough cloud hardware to run each instance and stream the image and sound to your screen. And over time, it will get better and better at doing so.

There's really no upside to having your own general purpose computing hardware unless you're really into child porn or something.
