Supercharger v1 and v2 cool passively. The v3 and v4 cables are actively liquid cooled. They’re designed to just stop if the sensors fail.

Tomographic detection has been around for some time. There was a company that commercialized this and had a more or less real-time Harry Potter style “Marauder’s Map” of your home for a security system but they did a lousy job commercializi

Nation states (like KSA) will likely pay very large sums of money to use this against their perceived enemies abroad. A small and exclusive clientele is how a company like this stays out of the lime light.

Fair. I’ve had a really good experience with the voice controls since I read a “cheat sheet” someone posted with common control commands.

Fwiw, teslas support pretty much everything via voice. You just press the right button on the wheel and say what you want it to do. I’m not disagreeing with your dislike for touch screens, but Tesla can do literally almost everything hands

Because very few species have been hunted to extinction. That’s directly contextual to the conversation. Both are a travesty fwiw, but habitat destruction is easily 10x worse when it comes to endangering species.

Domestic cats are the number one killer of songbirds globally. This is factual. Some strays used to stalk our bird feeder and I was finding dead goldfinches decapitated. Then we got an outdoor dog.

IIRC, NASA and SpaceX are working on a study to see if Dragon can do station keeping for this exact reason. NASA is doing a great job hedging their bets in a very tricky political climate.
