I once said that the current “AI” is just a excel spread sheet with a few billion rows, from what all of the answer gets interpolated from…

Maybe not in a flashlight, but the scientific industry would be very pleased with them. Sterilize water and all surfaces in a second? Flash with 200nm light.

This was an yet another glorious episode from veritasium.

I hope we get well past UVC LEDs. (i.e., shorter wavelengths) UV LEDs are already available. Unfortunately, this progress will stop before X-ray light. With +1 KeV energy, you pretty much must blast off the electrons from the atoms to emit X-rays, which an x-ray tube already does. Or by peeling off a piece of scotch tape.

Windows: $ insmod < “http://shady-ring0-blob-from-internet.sys.cn” What could possibly go wrong?

I ate both. Nothing really happened to me, but the matrix has been glitching though…

Shorter version: Operating systems set up hardware locks and protections to confine processes, and once set up, they cannot be undone. (the hardware + OS denies modifications to the security policy)

• Attacker broke out from the app sandbox. (attacker can run code in the infected process)
• Broke out of the process. (gained root access; attacker can run anything)
• Broke into the kernel space (gained 100% control over the hardware)
• Corrupted some kernel memory via a damm magic MMIO accesses nobody knows (hardware vulnerable)
• Bypassed protections that kernel set up earlier such that it cannot accidentally modify itself.
• Finally broke the kernel via hardware exploit thus the attacker got rootkit level access.

Getting arbitrary code execution and root access is one thing, but breaking out from the damm kernel configured hardware protections is insane.

They basically managed to flip a “read-only” switch to “modify-as-much-as-you-like”. The infected device at this point is broken beyond repair, as the firmware(s) may have been tampered with. End result is a terrestrial spy brick.
