99.9% of all software that has ever been written is utter shit. No matter where you go, all you'll find is terribly written, bloated, slow, and in general, bad software. And that's just individual software, not code. If you're talking code, just about every line of code that has ever been written is shit, too.
Hell, it's not even just software;
I'll finish writing this later, for now have a table of software:
| Shit | Less Shit, but Still Avoid | BASED |
|---|---|---|
| Java, Ruby, Perl, x86 ASM, Bash, Go, JS... | C++, C, Python | MIPS64 Assembly |
| bash, dash, ash | fish | zsh |
| GNU Coreutils | BSD's utils | Might as well just make your own... |
| GTK | Qt, curses | Avoiding interfaces at all |
| uClibc | musl | glibc |
| Matrix | IRC | XMPP, any basic plaintext protocols |
| ed, nano, emacs... | vim | neovim |
| GNU screen | tmux | TTYs |
| All terminal emulators | kitty | xterm, TTY, setting /bin/[z]sh as your init |
| tcc, clang | none | GCC |
| JSON, CSV, TSV, YAML | none | filesystem hierarchies, plaintext |
| Absolutely any and all "database" systems | none | filesystem hierarchies |
| PulseAudio | OSS, PipeWire | ALSA |
| Apache, lighttpd | nginx | Mongoose |
| MIT, CC0, most other licenses | BSD | {A,L,}GPL |
| Javascript, JQuery, PHP... | CGI | Mongoose, or best yet, plain HTML |

| Pretty much all browsers | lynx, librewolf | qutebrowser |
| Any and all file managers | none | ls, cp, rm... |
| Most graphical image viewers | viu | fbi, imv |
| KeePass{X,} | KeePassXC, pass | Paper, don't store your damn passwords on your computer |

| X, most X window managers, some Wayland compositors | i3, Wayland | sway |
| dmenu, ffcast, all other X tools | none | rofi-wayland, grim/slurp, wf-recorder, waybar, swaymsg |
And here's stuff you should absolutely never use or do that don't need an alternative:
