I love learning new Smallpox Eradication Lore.
The second scenario omits the details about continuing to create and submit pull requests after takeover, instead just referring to human farms. Since it doesn't explicitly say that it's still optimizing for the original objective criteria and instead just refers to world domination, it appears to be inner misalignment (e.g. no longer aligned with the original optimizer). Did the original posing of this question specify that scenario 2 still maximizes pull requests after world domination?
I just checked the DoE guidelines on this, and I think fairy lights are actually exempt! Here's the relevant paragraph (bold mine):
"Lamp" here should refer to each individual bulb. Referring specifically to the Prextex lights you linked: They do not have a medium screw base (=the standard E26 base you see in most house lamps), lumens per bulb is below 310, and each individual bulb is at just 2.5V.
This explains the lack of any "discontinued" notice or sudden price spikes or panic buying. Also, looks like there are plenty of loopholes for continued incandescent usage. It'll be a pain, and it's a dumb rule, but it's surmountable. This will be yet another area in which knowing the specifics of the dumb rules will advantage some people over others.
