If you mean why do devs still use the terminal over GUI programs, I'd say a big reason why is because its kind of like its own universal GUI. Take git for example. If I use VSCode and you use Kraken for example, and you have a problem with git and ask for my help with it, depending on the complexity of the problem I might not be able to figure out how Kraken works or even what the issue is. We could fix that by settling on one GUI git program, but you say we should settle on Kraken and I say we settle on VSCode. The terminal meanwhile is the default choice, because its on every machine by default and is compatible with any other tool you use.
