My main gripe with Discord is the somewhat ephemeral nature of it, due to the search being horrible, as well as not publicly indexed nor easily accessible without an account + an invite to a specific server.
The blue tint disrupts your sleep cycle and helps keep you awake when driving at night. There's definitely a trade off to be had depending on where these lights are located though.
It is very nice not having to write code from scratch by hand, but I have noticed that by not doing so, my innate familiarity of the code absolutely craters. Making manual changes to the code suddenly becomes a much more tedious and less confident process, and in many cases I am not sure that it's a net benefit (at least in a situation like mine, where there is no oversight and things go straight to prod.)
