The reason behind might be the same: we have far more computing power than ever, so we start to abusing it by spending lots of it on visual elements which is good to have but not essential.
Doesn't it have to do more with current software development practices? The requirement for reusable code , and the practice of coders having no loyalty and switching companies every very few years leads to the adoption of anti-optimizing standard practices. If Carmack was making doom today he would be ridiculed for not bundling his functional code and looked down upon for reinventing math functions. The idea that speed doesnt matter is just too prevalent
I agree on the point of websites getting slower, but not on that it doesn't add value. Website nowadays replace a lot of what would've been desktop applications ten years ago (see Dropbox, Slack, Google Docs, ...). It's not perfect, of course, - a lot of data now lies on PCs owned by somebody else - but skipping the installation/deinstallation part easily while also knowing that the app only has limited access to my PC is absolutely awesome.
It seems to be a constantly repeated myth or something of no consequence. (one article I read said LCDs have 2 ms higher latency than CRTs, which I would count as of no consequence)
Back in 2011/2012, when I got Rock Smith, I used a dslr camera to determine the latency of my LCD compared to my old CRT. Just took a snap of a ms counter racing up on both screens (mirrored). Can't recall the exact difference, but definitely much more than 2ms. I measured because I noticed it during gameplay; I'm pretty sensitive to delayed video/audio, but not 2ms sensitive - that's one beat off at 30.000bpm. You can use that technique to check for yourself with a more modern display.
I ask for evidence because I’m not the one presenting the claim and suspect it’s no longer true.
Similar issue for emulation: for the SNES games on the Wii emulator, the game was much harder because you have to adjust for noticeable lag between your presses and the response. I also saw that on the Virgin in-flight Pac-Man: with their emulator, you have lag that makes the game harder. I was able to get a lot farther on the first try by playing on a classic machine.
KISS, SSR is fine for most the time for web pages!!!
One exception to the above rule of SPA framework is mithril.
However, I understand not everyone can code in LISP/Scheme way. So I don't blame it for not being more used and popular than React camp. However, they seems to have JSX support now, not sure if the performance is still the same when using JSX.
The conclusion in this article is that it's not getting slower though.
