I was at the Museum of Natural History in DC a few weeks ago and got hit in the face more than once with those stupid things. I complained to the curator's office before I left, and I'm glad I'm apparently not alone in doing so.

Nobody's going to run off with your camera. Just ask someone nearby to take a photo of you.

The batteries must be replaced or recharged:

1) When the transmitter has been in use for more than 1 cumulative hour; or

2) When 50 percent of their useful life (or for rechargeable batteries, 50 percent of their useful life or charge) has expired, as established by the transmitter manufacturer under its approval.

This has zero chance of becoming law.

Okay, good work. But in their model, do they make the assumption that everyone on the continent is trying to make for Glacier National Park? Because, now that they've told everyone that's what they should do, I think their model should account for that.

The legal theory is the delegation of powers. Congress delegated the power to write legislation within a certain scope, breadth, and depth, to the executive branch of government, authorizing it to set up an agency to manage same.

Congress has the right to delegate its power to legislate to other branches of government. It is unfortunate, but we are learning now that it has delegated pretty much all of its power.

Well that's how democracy dies, isn't it? To the sound of thunderous applause?

This isn't legislation. It is executive decree.

"Fully autonomous weapons are not unambiguously bad. They can reduce burdens on soldiers. Already, military robots are saving many service members' lives, for example by neutralizing improvised explosive devices in Afghanistan and Iraq."

A robot that neutralizes an IED is not a "fully autonomous weapon."

The governments will simply say "come and take it, if you can."
