This is ironic. College freshmen said the exact same thing when I started college. In 1978. Social Security has always been eminently fixable by extremely modest changes in taxation. It is folks with attitudes like the one expressed abov

The legal problem is: which humans? It's one thing to say that on average, the system will save lives compared to an average human. But perhaps the human in the car is above average. Is the car safer for them? Perhaps not. How can

I think a more apt analogy would be if you would disqualify doctors who don't know the nucleotide sequence of the genes that code for the cytochrome p450 enzyme process from treating your cold or flu. The left pulmonary veins are gross

In immigration courts the judge and the prosecutor both work for the same branch of government. There is no illusion of independence. The purpose of the "court" is simply to provide pro-forma due process during an administrative

The largest single source of bankruptcy in the US is medical debt. So you are essentially equating having a family member need serious medical care with mendacity, laziness, and general moral failure. Is that really something we want to d

The NY Times published an article[1] in 2015 that asked a few public health experts to estimate the loss of life in the US due to the fraud. An MIT study claims over 1,200 premature deaths in Europe due to the fraud. [2][3] [1] https:&#x2F

I scan all my receipts, and every gas station receipt has a date and time stamp. How accurate they are is anyone's guess. I also always use a credit card for any transaction which gives another 'I was there' proof point.

As I loosely explained in another comment, you essentially never see repeats. The replay happens at the speed of light, and time stamps are broadcast once every 6 seconds at 50 BPS. The receiver sees the rebroadcast because it captures the

TLDR: you essentially never see repeated time stamps. GPS time is broadcast in the very low bit rate (50 BPS) NAV message, once every 6 seconds. In between the receiver counts at the chip rate (1023 kHz) just counting signal transitions. A

Full-blown spoofing, ie, being able to generate a 'valid' sui generis GPS signal is effectively ruled out by encryption. However a replay attack that uses a valid signal received at some other locate re-broadcast at a second pla

All of those things require some alternate source of ground truth, e.g., a trusted clock. There is no such thing in GNSS systems. They are the ground truth. There is no way to combat a replay attack without some second source which woul

You don't so much land on a comet, as dock with it. And I think they kinda less-than-succeeded at that.
