I don't think you need fear that. Unless it is made illegal you will always be able to buy a 'computer' on which you can write your own code. However, as the great mass of folks who are only users of what we now call computers (web, email, twitter, what ever) move on to the appliance that replaces them, the cost of a computer will go up because the volumes in which they are sold will go down.
In '78 I paid $800 for a computer kit which, when assembled, was waaaaay less capable than a Raspberry Pi. But there were maybe 10,000 ever made. My prediction is that the next 'gap' will be when the big players (HP, Apple, Asus, etc) move on to selling appliances for users.
Laptops might get eaten in this gap. But there will be the equivalent of a terminal program in the appliance thing you are using so you can program over the network. If you want to run code on the machine that you are typing on, you may have to have a 'deskside' type computer, which is living off the ecosystem of server machines.
Other risks are disk drives that are too smart for their own good (built in DRM as an example). Hard to build one from scratch, but flash is ok for now.
Overall you'll experience the same sort of changes car enthusiasts did where cars became less and less a motor and a transmission and a body and more all of that and a complex proprietary feedback control system to run it. Of course many kids these days don't care that they can't put 'glass packs' on their ride, they have other things to customize.
