Surge suppressors do not drop extra voltage to ground. They selectively short out surges between whatever two conductors have a high potential between them.
No ground conductor means there cannot be a high potential between it and anything else!

yeah they are selling “wireless home internet” hard now, can’t have people using their phone hotspot for that.
Guys, he made the joke!
Have you tried Scala.js ?
fyi the NeXT OS is called NeXTSTEP.
Fun fact: a US nickel weighs 5.000g, and 5 US quarters weigh 1.0000oz
FYI, banks do run exactly this type of analysis inside their own system to get around not being able to share your account activity.
Yes, the center (neutral) is connected to ground somewhere, but is not a suitable ground reference - because current on the neutral creates a voltage drop along the neutral conductor. A North American outlet box has Hot (L1), maybe another Hot (L2), Neutral, and also an earth/ground conductor.
Neutral is not ever treated as ground; it’s impermissible to connect it to any bare metallic surface. Other than not being switched, and being the side that ends up on the threads of a light socket, it’s handled the same way as a hot/line conductor. Just like a 240V system.
It would dissipate static fine, if you were allowed to touch it.
I think that’s incorrect. The ground pin is a dedicated equipotential reference bonded to the earth via an acyclic wiring path which carries no current. It does go pretty directly to the ground rod via the breaker panel ground bus. Neutral happens to be connected to it at the entrance panel for fault clearing, but not really for any other reason.
Since all metallic chassis, pipes, ducts, etc are connected to it and it is available pretty much throughout a building, it is a logical place to connect ESD-prevention gear, even if the earth has little to do with that. (But, a grounding electrode system installed to code should have less than 25 ohm impedance to ideal earth - not exactly a “poor” conductor)
The thing is, it may not “break” them but may introduce difficult to localize unreliable operation - which you may even explain away as buggy software.
IC’s, especially small feature size CMOS, absolutely are subject to ESD damage.
By definition, the 1% are the top 1% of earners in the population, so there are 8,100,000,000 * 0.01 = 81,000,000 of them, not 400.
The richest 400 are the 0.000005%.
The 1% line in the US is at $819k a year, and $60k worldwide.
Betavoltaics have been around for 40+ years. https://en.m.wikipedia.org/wiki/Betavoltaic_device
This device generates microwatts. You’d need thousands of them in parallel to power a typical mobile phone.
All of their tech job openings are in India or Vietnam. I’d have assumed a major US health data handler would be developing onshore!
Performance is the major flaw with microkernels that have prevented the half-dozen or more serious attempts at this to succeed.
Incurring context switching for low-level operations is just too slow.
An alternative might be a safe/provable language for kernel and drivers where the compiler can guarantee properties of kernel modules instead of requiring hardware guarantees, and it ends up in one address space/protection boundary. But then the compiler (and its output) becomes a trusted component.
