    The slide remaining open is actually a design feature, called a "slide lock" or "slide stop", that's usually put into gun designs to make them faster and easier to reload, but it's not universal - Kel-Tec's tiny pocket .380 didn't have room for the levers without adding at least a mm to the thickness - we may all think of Apple as being obsessed with "thin and light", but they're not the first company to sacrifice functionality for pocketability.

    Strictly speaking, "automatic" is probably best thought of as the category that includes both "semi automatic" and "fully automatic" operation.

    In the Kellerman study, 37 of the reported deaths were suicides, constituting 86% of the recorded deaths. The remainder included husbands shot while beating their wives and intra-family drug deals gone bad.

    shot, not shot at. PCP can do some crazy things to people - taking a shotgun slug through the heart, leaving a hole over an inch and a half across, people have been known to continue fighting until their brain runs out of oxygen. I can't be arced to look up the news story, but this actually happened.

    Granted, many cops are frightfully bad shots, but let's not ignore what the grandparent actually said - these are not magic wands, they are not death rays, and there are lots of places you can poke a hole in a person's body that won't immediately stop them from behaving in a violent way.

    First thing you need to know about synthetic biology:

    Anything you can make in a higher life form, you can mass produce in a beer-brewing kit, with enough man-hours engineering the yeast. If this works, it'll be ten years until a recombinant form is available from some biotech firm; most of that will be spent in the approval process because slicing out a gene and slapping it in a plasmid is something they teach undergraduates to do these days in "Intro to Biotech".

    You assume EVs will be expensive forever. And that fuel costs won't rise, making EVs seem cheap even at current prices.

    These are assumptions, and are not guaranteed.

    And this is why IMR and LiFePO4 are displacing LiCo chemistries - the oxygen is better contained. LiCo batteries evolve oxygen gas when heated, making their failure spectacular, violent, and when packed in metal cans, very nearly a detonation. LiNiCo offers some advantage in stability, without sacrificing the energy density that keeps people using LiCo. IMR (lithium manganese spinel) is very stable, requiring an external heat source or abuse like short-circuiting to fail spectacularly. They can also deliver more current, since LiCo is limited by how fast you can draw them down without making them likely to blow up by forming metallic lithium inside the cell. LiFePO4 store less energy still, but can deliver thick chewy amps because of its stability.

    As I understand it, no electric cars use the old LiCo chemistry, or we'd have seen a far more exciting fire in this Tesla.

    Your microwave oven will probably become much more mass-efficient and somewhat more energy-efficient.

    It might enable radars of similar size, cheap enough to mount in every air vent in your house and able to direct the chilled air at people; combined with similarly miniaturized heat sensors, you'll find yourself cooling off or warming up much more quickly after coming inside.

    It's probably cheaper than any other method of managing their condition like amputation, disability payments, and nursing homes.

    Keeping diabetes from going from the "cheap to manage" to "terribly expensive" stage is probably, like most other healthcare things, a net savings once you get to even the medium term.

    If they wanted to screw Apple, they could mandate a fixed-pinout version of Lightning implementing no logic in the cables, with reversible pinouts for USB 3.0 and tell Apple to get on board with their pinout with a firmware update. That'd solve at least four problems at once - Apple's ego, shitty knockoff cables, fiddly charging cables, and e-waste. Anything else is just gravy, but there's probably at least one more significant benefit.

    Oh, right. USB3 charging current and data-rate become the expectation. :D
