"on their way to ending car ownership, Uber and Lyft got sidetracked and ended up clogging cities with more traffic. Between 2010 and 2016, traffic congestion in San Francisco increased by about 60 percent, and Uber and Lyft were respo

It is an abject failure of our amplification systems, notably HN and Stewart Brand's Long Now, that we are listening to two Baby Boomer musicians debate energy policy. Who cares what Eno and Byrne think about nuclear power?

Interesting. The resurgence of "local idiot" nationalism has led to virulent anti-expertise in general and anti-environmentalism in particular in Poland, East Germany, arguably France ... what is denialism like in the Netherlands?

No, I based on attending SparkConf between 2015 and 2017. You could probably assemble half of it just by reading summaries of Matei's keynotes.

The article says China's deployment plans are being derailed by cost and popular attitudes towards nuclear. The cost of new tech in turn is mostly driven by the chicken-and-egg problem of deployment. So you have to solve deployment, wh
