So I haven't watched this video. But in the age of deepfakes, with a click bait title, why should I believe video anymore? Especially "rare, lost" ones? And presumably ones with a point to push? What do HNers do to assess the provenance / authenticity of video in 2026 and beyond?
Can't confirm if it's real or fake, but I skipped around and it's just the same "predictions" he's been making for a few decades. He's going to build the biggest bestest rockets, we'll live on Mars, he'll make the fastest car and it will also be able to fly, etc.
His disgusting father never patted him on the head and told him he's a good boy for reading Popular Mechanics and sci fi novels, and now we all have to live through this.
The time-honored way of learning about monads is to write a monad tutorial. Monads provide an order dependency (that along with some hidden strictness for I/O and the like) which allows the side-effecting to be isolated from the "pure" functional side of things. The purely functional Clean language had an explicit "world" variable that you could pass around to whatever side-effecting functions you wanted. And it had uniqueness typing so that you couldn't accidentally refer to the same "world" twice. You can think about monads as being a way to hide the crufty "world". A lot of the mystery around monads comes simultaneously with a whole bunch of other newness in learning Haskell (lazy evaluation, HM type system, differing syntax, algebraic data types, currying and partial application, functional programming, etc.).

You can do a lot worse than a $55 temperature controlled hot plate. Plus you can watch the magic happen. Of course that only works for single sided boards. I've been very impressed with the results.
I wonder what ever happened with the stream poisoning effort on a creek that ran through his ranch. That was bit of a thing growing-up back in Montana in the 90s, where the billionaire outsider wanted to poison the stream to kill off one species of fish to encourage another species.
Isn't the concern with over the air updates and back-doors? As in, if the citizens in county A buy country B's cars, and now there is a tiff between the two countries, country B could potentially brick all of those vehicles in country A.
That is just another variation of geopolitical worry. Nobody will do this unless there is a geopolitical situation happening. If you are going to war then bricking the enemies cars is useful. Otherwise it is harmful (even if you do it accidentally you lose trust and so nobody will buy from you again - which is why so often rollouts are done slowly - if it doesn't work you only have a few customers affects and can spend more than a car's value on techs to fix them thus ensuring you don't lost reputation)
