What happened to my JavaScript phone? | JS Conf 2019

Not long ago, it seemed like JavaScript devices were going to free JS developers from the constraints of the browser and let us control every aspect of our lives as easily as we once controlled hover menus.

We have the same two operating systems, the same two app stores, and same option to write a native app or push people to save what is still mostly a bookmark. How did we cover so little distance, given the enthusiasm, resources, and potential that appeared to exist, and more importantly, how close can we come to a JavaScript phone today?
