Every time something like this comes up, I imagine a bunch of giddy "world-changers" sitting behind Mac Pros with Retina displays and T3 lines, building something that works great under those conditions, and then convincing each other that they've helped people over $16 microbrews.

I know this is a caricature but it's how I get my kicks.

To wit, the conditions that the engineers inhabit in their lives has basically zero resemblance with the technology experience of the vast majority of people. Designing websites for 4K screens only, expecting <20ms latency over home lines when everyone else in the house is streaming video to their own personal devices, etc. One thing we can do collectively as an industry is put in place guidelines which steer development to minimalism and attention to the resources available to the median user.
