Something that got mentioned in one of the better geopolitics forums I keep an eye on is that the hardware apparently used in this attack is very, very low tech. Basically hobbyist grade shit that hundreds of thousands of relatively competent engineers around the world could build using entirely off the shelf parts
Those are apparently pictures of some of the "drones" that were part of the attack, but shot down by Saudi forces. If you can bring 5% of world oil production to a screeching halt with a couple thousand bucks worth of gear off of aliexpress, the future might fucking suck.
Above my pay grade. I get it, in that I get that intrabank lending rates spiked and that's bad so the fed came in to provide liquidity (which is their function after all) but I don't know which (if any) of the floating theories are right. We're well into monetary voodoo here.
