Technologies I'm excited about

Lighting

The brightness of the outdoors on a cloudy day is 10,000 lux. The average indoor room is only 100 lux. A conservative estimate is that it is an order of magnitude brighter outdoors than it is indoors. This has far reaching implications for our health, as it affects our circadian regulation, mood, focus, even eyesight.

I feel confident that 100 years from now we will have a much brighter indoors, but it's not an easy problem. Just buying a ton more lightbulb is cost prohibitive, and there are tradeoffs to light quality and diffusion (it's quite unpleasant to have an extremely bright light in your home).

Technology driven education

There exists so much room for technology to track the learning state of a student and create the most efficient path forward. For some reason most of our learning technology does not intelligently track this learning state, but has you go through lessons in a pre-determined order. This is wildly inefficient. You should only be spending your time and mental effort on things that yield the greatest return.

Math Academy has made great strides.
