The last change that we make in the US was implemented in a couple of years, so it's really not a big change.

Here in Arizona we have to deal with everybody else seemingly arbitrarily changing their clocks, so it is possible to deal with it, and it's really not that bad.

The sooner everybody wakes up and realizes that there's not need to change clocks the better IMO.

You're not actually believing this are you?
He did put together some nice animations, and pulled the $1 figure out of... well I don't know where, but where's the engineering analysis and the business plan?
Why does he think he can be that much cheaper, faster, and more efficient than any other type of transportation? Where are the efficiencies gained?

Actually, the random unassigned seating method that Southwest uses is the fastest.

Unfortunately other airlines will never do that because they have to get rid of all their perk levels.

You mention in your post "government power centralization bad", but then in your signature seem to imply that Liberalism leads to more authoritarianism. I see things just the opposite, especially in the Trump era. The libertarian wing (I call them the liberals of the right) of the conservative movement is getting more and more marginalized, and Trump seems to be moving the party more an more authoritarian every day.

What exactly are average people running on their desktop/laptop that doesn't have a web-app equivalent? I swapped out my family computer for a Chromebox a couple of years ago and no one even really noticed because all they ever used was a web browser.

I really haven't understood all the hype around the Essential phone. How is it fundamentally different than all the other smart phones on the market?

Oh, and the iPhone has a pretty small market share, so calling something an iPhone killer seem to be setting a pretty low bar...

Nothing has been able to kill all life on earth for the 3.8 billion years that it has existed, and I believe human intelligence gives us a huge advantage to surviving catastrophic events, such as the one that wiped out the dinosaurs.

If he's afraid that we will kill ourselves, then what's to prevent us from doing the same thing in short order on any other planet we colonize?

... It's just more accessible these days and more practical due to the huge increase in computing power. Back in the day, it was required to reduce the data (images, etc) to a much smaller set of features that could be fed into the AI algorithms. Now there's enough computing power for the AI engines to determine good features on their own.

Even though you can train a neural net to recognize e.g. hotdogs by just feeding it a series of pictures of hotdogs, and, of course pictures of things that might be mistaken for hotdogs... I believe it's still best to have some domain expertise in what you're trying to get the computer to learn. If you want to get into AI for self driving cars, for instance, it would be good if you knew a bit about image processing.
