The Raptor engines are unusual in that they can throttle down to 40% but as far as I know they still rely on turning some on and some off during different flight stages. If not takeoff and max q, for sure during landing. That coordination has to be super complex...

For context, the engine has been under development for a decade and testing for five years. It's a smaller engine than usual on heavy lift vehicles. It's height is 10 feet. The F1 engine from the Saturn V is almost twice as tall, could fit a Raptor sideways in its nozzle, and develops over 3x the thrust. But where the Saturn V has 5 F1s on the bottom, BFR has 33 Raptors. About twice the thrust in total.

This test is a big deal for Space X. A TON of their future plans hinge on the Raptor.

That is the thing! You see, the question raised here is how any one country can regulate and judiciate a technology when it also has the power to wreak havoc in our own backyards.

The only thing, from a moral point of view, is first to check our own uses and growth, and only then can we be able to regulate and catch our adversarial nations if they go beyond the line and can impact homeland security.

This is the same as the advent of Nuclear technology. Back when we first developed nuclear weapons, within four years of our creation, Russia developed its own. Fast forward to a few decades ahead, several other nations developed nukes as well. So, if I may ask, who gave others the leading light and inspiration to do that in the first place?

And worst of all, we are the only nation in the world who have used nuclear warheads practically and killed hundreds of thousands of people - some are still reeling from their effects.

Therefore, we cannot ever claim that we are doing this for the defense of our great country. It is in fact more of a fight to become "who is the real lord" rather than safety, something that will eventually become the reason for our collective demise. And the same fear I now have with the limitless destructive possibilities of AI.

I am quite sure many of my fellow Americans must have the same fear as I do.

Article is a pathetic paid propaganda hit piece.

Google switched maps and gmail domains to be subdomains of google.com, so whenever you use maps u give google.com your full location permissions - but noone bats an eye or even "concerned".

Sorry - I'm way way more concerned about us gov spying on me then Chinese - they can't reach me to f me over.
