I cringe quite hard when I see projects with either of these now-cliche catchphrases. It's crazy how many people use them.
I, too, only use software that is "made with binary".
I still prefer it to the "performant and beautiful" Electron made famous. almost all of the applications that said that were neither performant or beautiful, unless you found web pages and their quirks more beautiful than native GUIs.
“Lightning fast” is no less meaningless in practice than “blazing fast”. Both get used extensively by projects in such languages as JavaScript and Rust, on projects of similar scope that nonetheless have at least an order or two of magnitude’s performance difference.
If the title claims "lightning fast" or "blazing fast", I expect to see quantitative comparisons to alternatives. Which operations are faster than in other programs?
alacritty is a Rust program that is promoted as uniquely fast, but is substantially slower than (e.g.) kitty.
