And, yeah. That whole "mobile is the future" thing really was so 2010. But mobile only turned out to be _part_ of the future. Everyone was so convinced that tiny plastic devices with no keyboards or computing power would supersede decades of awesomeness that was, and continues to be, the personal computer.
"Mobile is the future" didn't pan out, similarly to how today's "enterprise is the future" fad is going to.
Developers should be able to see past all this noise, choose a compromise between what they enjoy doing and what makes money, and go do some cool shit.
