Sort of makes sense, the body is a machine and will get worn down/depleted at some point and not some infinite bag of holding. Surprised its as low at 4650 calories though, figured marathoners + swimmers and such could burn more.

Yeah the centralized protocol should be easy to manage because it's largely static. I'd add a b_scope_ver type field. As scopes are added it gets incremented. A static doc describing the version can be fetched and cached permanently on demand when a new version is seen, maybe. Can even serve the static docs out of s3 even.

I'd argue for it to go the other way. Driving has a large cultural component -- people tend to drive how others around them do. Once autonomous cars hit some critical mass lots of human drivers are going to start mimicking how they drive which is probably a fair bit more conservative than most of these people in big cities.

A few of us at my work bought some similar type devices, but with two wheel, like a mini-segway. They are definately more of a toy -- they're a lot of fun to ride around on but not that appropriate for day to day transport. They're actually very stable and intuitive and very easy to get on and off. The learning curve is < 60 seconds. The big issue is that with the small hard wheels small bumps cause it to lurch and can throw you off face first. Had someone with a minor wrist sprain and a fractured elbow basically hitting small bumps and falling off. Would surely not want my grandma using one.

It'd be savory/savoryness

Nice, it should however display what the next exercise is during the rest timer countdown so you can get ready for it. For the ab crunches it takes a bit of time to get on the ground if you don't see it coming.

Well I'd imagine they left it off the customs declaration

Writing the formula down on a piece of paper doesn't by itself count as thought though. I haven't read the book so can't really comment what the author would say, but to load the formula into your brain and think about it in a useful way is very different than plugging it into a calculator or reading the formula.
