Would an upgraded version of this that was actually capable of capturing the progress of a single laser pulse through the smoke be a way of getting around the one-way speed of light limitation [0]? It seems like if you could measure the pulse's propagation in one direction, and the other (as measured by when it scatters of the smoke at various positions in both directions), this seems like it would get around it?
But it's been a while since I read an explanation for why we have the one-way limitation in the first place, so I could be forgetting something.
It is not different phases, but it is a composite! On his second channel he describes the process[0]. Basically, it's a photomultiplier tube (PMT) attached to a precise motion control rig and a 2B sample/second oscilloscope. So he ends up capturing the actual signal from the PMT over that timespan at a resolution of 2B samples/s, and then repeating the experiment for the next pixel over. Then after some DSP and mosaicing, you get the video.

The point here isn't to measure the speed of light, and my general response when someone asks "can I get around physics with this trick" by answer is no. But I'd be lying if I said I totally understood your question.
Forcing children who aren't normal to be normal is child abuse, and your comment is an attempt to perpetuate the kind of abuse that I was subjected to.
Besides that, IMO hiding hardware details from the developer is the worst thing about Arduino. The hardware details matter and it's far too easy to get footgunned by some implementation detail hidden from you.
But really, esp-IDF isn't that much more complex, nor are most of the other native frameworks. It's a bit more verbose, but esp-IDF provides helper libraries that replace almost everything Arduino provides, but in a way that is actually designed for the hardware and doesn't have to do things like lookup pin numbers in a giant table for each and every gpio call.

1. Trump was president in 2019 and 2020.
2. There is an important difference between a bureaucrat calling up someone at Facebook at arguing a position about policy and the chair of the FCC threatening to remove broadcast licenses. Notable, Supreme Court has even weighed in on the former and found it well within the rights of the government to do.
