In just a few years around 2007-2012 we got Oculus, Nest, Ring, Blink, Fitbit, Beats, Oura, Square, Pebble, Tile, Dropcam, SmartThings, Makerbot, Neato, Raspberry Pi... All pure consumer hardware startups with popular products and successful exits. So it's not like the category is somehow fundamentally not viable. It just needs VCs and consumers to both shift from the smartphone-only mindset and start taking some risks.
