A lot of the features you mention were already there in XMPP 20 years ago. I've lost track of the standard a long time ago but I assume the rest have been added through extensions.
I think the issue is that people are adjusting what they see on screen instead of adjusting their environment (i.e. room lighting), even when they are totally able to do it.
A dark mode could make it bearable to work in poor light conditions but won't improve on the fact that it's already a non-optimal environment.
I think this piece shows the range of his musical expressiveness, apart from his virtuosity or synth programming skills. Just a piano passed through a flanger effect with some ambient sounds.
The electronic bleeps in that track are recorded from a handheld electronic game (Bambino UFO Master Blaster [1]). Talk about giving a whole new meaning to those sounds.
Spaces work well for indentation. You could argue here that typing one character (tab) is more efficient and maintainable than writing N (also semantically more powerful).
The real problem comes when people start aligning things on the middle of the line.
As long as source code resides in plaintext files, writing in columns (i.e. vertically aligning blocks of text) seems like an excessive endeavor with little gain.
We are not typesetting; formatting resources should be kept to a minimum to make the code easy to handle in plaintext. Fortunately, code is restricted enough that we can do pretty well without those.
You don't write spaces to align text in Word: it's a nightmare to maintain and the software provides better tools for that purpose. Why do we still write code as if we were using a typewriter?
You may think you are improving readability by aligning columns of text, but then, the impossibility of standardizing such baroque formatting rules goes against that. Furthermore, you are preventing people from using a variable-width font, which is actually better for readability.
I've been using Verdana for ~10 years. I've tried others but keep coming back to it. It continues to be a very consistent and elegant design for screen.
I feel like many times it's not that the message doesn't get read but that it doesn't persuade the recipient to make the time to write a response.
Shortening the text not only transmits the message more efficiently, it also allows the recipient to feel comfortable with writing a one-liner reply. You are actually lowering the threshold over which the person gains the will to start writing a response.
