In a literal translation it would be, but considering it’s not a big bang, but the big bang, it’d be “Urknall” which I’m not sure how best to literally translate to English, but it’s something along the lines of “bang of origin” or “original bang”.
That doesn’t make the tweet any less wrong though, this is just semantics.
For me it’s pretty likely to replace it, at least on my laptop. Don’t get me wrong, I love Plasma, but per-screen workspaces and native window tiling are two features I never knew how much I needed before I tried out Hyprland some months back, especially on a single screen. While I’ll definitely miss the desktop panels and extensive settings menu, I’ll give those up for the other features without much of a second thought.
