> Misaligning only some pads while others are perfectly aligned isn’t possible
It's possible when your pcb-making process is on the odge of what designer wanted. Some pads on some boards may be not perfectly aligned in such cases. Or the board was heated not enough or in too short time and not all balls melted properly. Or it cracked under stresses because designer put too much vias in one place near the chip.
> It’s an all-or-nothing situation—either everything aligns, or nothing does.
In theory, practice and theory agrees. In practice, it sometimes does not.
I believe you forgot to quote "unless something’s seriously wrong". Your counter examples seem to describe exactly that: something going seriously wrong.
I noticed this effect on silicone tray intended for freezing water cubes. It would seem that it should be safe for freezer, but after freezing it, cubes were partly colored by silicone part of tray. I won't use silicone for freezing anymore. Those trays for baking are not that confidence-building either. Good fast test if you should buy anything for food - if it smells of fresh car or plastic when new, don't use for food.
But Ford doesn't profit off those ads. Now they can deliver their own ads and capture some of that profit for the shareholders. Not being distracted is your responsibility, not Ford's, so they have clean hands.

And people storing other people's personal data end up with fines if they don't remove the data on request. The whole situation got so bad, that timescale had several bugs which prevented U and D of single records, you could only delete a shard. At least C and R is fast.
> the pods need to hang out near the surface to receive signals and to launch missiles, so they have a high risk of being detected before they can be used
You can now send encoded sonar pulses. With good microphones on pods, you can communicate over many many kilometers and those commands can be pretty short, no need to "real time fpv", just "target a ship currently at {X,Y}".
Just "infinitely curious individual" is a bookworm. Hacker would also like to tinker with the rules underlying the systems to see how things might break. So bookworm + tinkering + wants to understand complex systems (hackers call it "to grok"). Systems - not only computer systems, also biological, physical and any kind of complex assemblages of rules.
Still not specific enough and doesn't evoke hackers. I consider myself a hacker but I don't consider myself "infinitely" creative, just creative in technical areas. So maybe technically creative individual? But those are more like Makers.
