Mark Wilson of Fast Company cooked a piece of salmon in a $1,500 toaster over called June, which has a built-in camera, temperature probe, Wi-Fi, and artificial intelligence. He says the the oven isn't very good.

[June] required nearly $30 million in venture capital to create. It was the brainchild of the engineer who brought us the iPhone’s camera and Ammunition, the design firm that gave us Beats headphones.

But the June's fussy interface is archetypal Silicon Valley solutionism. Most kitchen appliances are literally one button from their intended function.

But where there once was just an on button, you now get a blur of uncertainty: How much am I in control? How much can I expect from the oven? I once sat watching the screen for two minutes, confused as to why my toast wasn’t being made. Little did I realize, there’s a checkmark I had to press—the computer equivalent of "Are you sure you want to delete these photos?" — before browning some bread.
