I could see AR/VR dev environments being viable enough to not get laughed at in 15 years, but there's no way we give up 2D displays in the majority by that time.
In 15 years? Potentially we'll have brain interfaces by then. Just imagine the job you want done and you'll "see" in your mind's eye the existing solutions in your code-base and then on the (contemporary version of the) internet.
