I doubt we will be in that situation, because then by definition all development will stop, and programming education will also stop. There will always be hardware or systems that you can develop on. Now what may happen (and is already happening in the case of mobile devices) is that rental content (streaming services, etc) will only play if they are on "trusted" hardware. So you can have a development environment, but good luck trying to watch Hulu on it. And the development-capable devices will be more expensive due to lower sales (most people would rather purchase hardware that can access the services they want).
