Since valid JSON is also valid YAML with the same semantics, it is impossible for it to be harder to write YAML than JSON, and no conversion is necessary.
The Atari ST's late 80s monochrome CRT looked a bit like an eink display, with no discernible flicker even at 72 Hz. It certainly looked very different from a 72 Hz colour CRT displaying a monochrome image. I think it used a different type of phosphor.
You’d need much lower than 72 hz for you to notice flicker. Regular VGA was 60 hz. Amiga interlace had noticeable flicker with an effective rate of 25 to 30 hz.
This is biology-dependent. With CRTs, I could detect flicker all the way up to 85Hz* (where it vanished for me). Made it a real pain to find a good monitor.

You are right. Perhaps I should've phrased it as "most people need..."
The Amiga interlace flicker was bothersome to me. When I got an Amiga 3000 with the built in deinterlacer / flicker fixer, it was like night and day...
The original statement, as phrased by their engineers, probably was something like “Our latest firmware regularly crashes your system, triggering reboots” (plus a few paragraphs with a highly detailed description of why that happened that only the engineers who wrote the firmware would understand)
This is what they ended up with after a few reviews with legal (“we can’t say ‘our’; they’ll eat us in court”) and marketing (“We need a less emotionally loaded way to say ‘crash’”)
Legal aimed to maintain just enough meaning in the statement to be able to say “we warned customers as soon as we could”; marketing aimed to make it a positive message. I guess that’s why ‘higher’ won over ‘more’.
In a cluster, all hosts must be updated for the flags to be exposed to the guests. That is why you must update vCenter first, which prevents the patched hosts from being rejected.
DEF (AdBlue) can significantly reduce NOx emissions. It's now standard in modern heavy diesel trucks, busses, etc. However, it's very rare to find it in light diesels such as cars and SUVs which often have real-world NOx emissions far in excess of what emissions standards allow.
DPFs remove visible soot from diesel emissions, but their actual benefit for health is less clear. They don't trap the ultra-fine, PM2.5 invisible sooty particles which are the most dangerous because they can penetrate the lungs and enter the bloodstream. These particles are associated with increased risk of cardiovascular diseases and cancer.
DPFs also tend to break down after a few years of use. Often, they end up being (illegally) removed by owners who don't want to pay for an expensive replacement.
DEF isn't that rare in passenger vehicles anymore. Ford's new line of diesels tend to use it, BMW and Mercedes use it, and I feel a couple of other 'new' small diesels are using it as well. It used to be rare, but I think enough people realized they can't meet standards without it and now they are all moving towards it.
Correct me if I'm wrong, but most regular consumer vehicles aren't required to have a urea/DEF system, but all the big trucks and commercial vehicles tend to.
Somebody was blaming this on trucks, but I'm thinking this might be the opposite - their small cars as it was with VW because they don't have these sorts of systems in place.
You're right. It's now light diesel vehicles that are the primary problem with regard to excessive NOx emissions. At least in Europe, where there are a huge number of light diesel vehicles on the roads.
But there are, of course, a lot of old pre-DEF heavy vehicles on the roads too that would not comply with modern emissions standards.
