There are 3 mines on Manhattan; is that correct?
Based on the info if you click into them, likely no. I would have expected them to be incidental materials from tunneling, but reading the description that's not the case.

I suspected this was because the vector units were not wide enough, and it seems that is the case. AVX2 is 256-bit, ARM NEON is only 128-bit.
The big question then is, why are ARM desktop (and server?) cores so far behind on wider SIMD support? It's not like Intel/AMD came up with these extensions for x86 yesterday; AVX2 is over 15 years old.

Aren't all DLLs on the Windows platform compiled with an unusual instruction at the start of each function? This makes it possible to somehow hot patch the DLL after it is already in memory
I believe you're thinking of the x86 Hotpatching hook[1], which doesn't exist on x86-64[2] (in the same form, it uses a x86-64 safe one).

Having given a zillion interviews, I expect that they weren't looking for the One True Answer, but were interested in seeing if you discussed plausible reasons in an informed way, as well as seeing what areas you focused on (e.g., do you discuss compiler issues or architecture issues). Saying "I dunno" is bad, especially after hints like "what about ..." and spouting complete nonsense is also bad.
(I'm just commenting on interviews in general, and this is in no way a criticism of your response.)
I think I said something about the stack efficiency. I was a kid that barely understood out of order execution. Register renaming and the rest was well beyond me. It was also a long time ago, so recollections are fuzzy. But, I do recall is they didn't prompt anything. I suspect the only reason I got the interview is I had done some SSE programming (AVX didn't exist yet, and to give timing context AltiVec was discussed), and they figured if I was curious enough to do that I might not be garbage.
Edit: Jogging my memory I believe they were explicit at the end of the interview they were looking for a Masters candidate. They did say I was on a good path IIRC. It wasn't a bad interview, but I was very clearly not what they were looking for.
I remember failing an interview with the optimization team of a large fruit trademarked computer maker because I couldn't explain why the x87 stack was a bad design. TBF they were looking for someone with a masters, not someone just graduating with a BS. But, now I know... honestly, I'm still not 100% sure what they were looking for in an answer. I assume something about register renaming. memory, and cycle efficiency.

It’s only older contracts and studio holdovers that are preventing simultaneous release (which has already been done at times).
I believe the Academy Awards and a few other things too also influence this. The rules to be eligible still very much favor legacy studios IIRC. But, with this that may change? Hard to say. I know that quite a few Netflix movies have had theatrical runs at random mom and pop theaters in Cali so they could meet eligibility requirements for the various awards.
The title is a bit misleading; it's running on an 8088-compatible CPU, and a 1 megabyte SRAM, with the FPGA containing the display adapter and drive controller, as well as the glue logic.
Honestly? I expected this to be talking about the MiSTer project FPGA core[1]. That has been tuned so it's capable of running the AREA5150 demo[2] which is an insane challenge (AFAIK the timings of the v20 break that demo). Not saying this isn't cool, but it's definitely not what I was expecting.

We could even go more basic... safe defaults when disconnected should be mandatory.
For example, if I pull the thermostat off my wall, the furnace should drop into a fallback mode that keeps the heat above freezing (I'm in Canada where this is a concern.)
I moved into a new house and did not set up the lawn irrigation system. Despite being disconnected from the cloud service, the system kept running its schedule, when I would have expected it turn off in order to conserve water.
I've said for years that any smart thermostat should have a bimetallic backup that controls maximum ranges and acts in the dumbest way possible. Just max temp and min temp for AC and heat. Nothing that should ever be hit... but there nonetheless.
When they introduced a mobile first UI onto a desktop OS...
When they forced mandatory Microsoft accounts...
When they started saving files that had no place being in one drive to the cloud by default and charging people for it...
When they announced the worst AI privacy disaster in computing OS history...
When their updates refused to install cleanly and bricked people's computer to the point of hardware damage...
Seriously thinking I might have Stockholm syndrome at this point. To me the best windows would be Windows 11's kernel and libraries with Windows 7's UI and apps. Because it's been all down hill (generally) since there.
