It is easy to look back on technology changes and see that we had plenty of warnings that we clearly missed at the time. VCRs gave way to DVD players, which in turn have given way to streaming services. Brick cellphones evolved into flip phones, which were swapped out for two-way pager phones and then wiped out by the iPhone model. Tape players gave way to the Walkman CD player, which gave way to the iPod, which also ended up in the iPhone model.
Sometimes, trends that seem obvious fail to materialize. Laser disks never got to critical mass before DVDs arrived on the scene, and 3D TV, which seemed so obviously next, wasn’t.
