But not from a knowledge engine. It makes sense if some rando just spouted off a date from the top of their head but this is the former world leader in knowledge capture and search.
This is true but it's much easier to understand in retrospect unless you have a very very gifted math teacher (or series of teachers really) when you start learning it. For most people learning algebra it's just another checkbox to tick for some reason. Plus pesky word problems that make you figure out the equations on top of that.
Now that I'm an adult I recognize what all of this was trying to teach me. But back in my school days it was just another thing I had to do between hanging out with friends.
IIRC, 5g is a much nicer generation for the carriers than for consumers. It can be more easily deployed with microcells on light poles vs requiring the tall cell towers. There's ultra-wideband, which is definitely faster, but plain 5g is roughly the same, just easier to roll out.
It'll probably be stored in something like a TPM, whose primary purpose is to make intact extraction of the keys difficult or impossible. A few keys might become compromised but in this scenario (unlike DRM decryption) it's easy to ignore those keys. There's always the chance an exploit becomes available and is more widely used, though, in which case it would definitely be less valuable.
These situations are almost always self-inflicted. If someone else hacked Google Cloud this badly then you'd likely have heard it from them first. And they probably would have done something significantly more destructive if their goal was harming Google reputation.
