It’s interesting that you keep confusing a concept (AR/VR) and a technology (screens, bci, etc). For the record, what I predict is: 1. In 15 years smartphones will be obsolete. The most likely technology that will replace them is retinal projection via glasses. Laptops and monitors will probably last a bit longer. 2. In 30 years, BCI will replace all other human computer interfaces, unless by that time humans will already have merged with computers on a more fundamental level. As with any examples of progress in human history things will appear to change slowly until they suddenly change very fast.
