Think of it like installing Linux. The first time it's absolutely not worth it from a time perspective. But after you've installed it once, you can reuse that installation, and eventually it makes sense and becomes second nature. Eventually that time investment pays dividends. Just like Linux tho, no one's going to force to you to install it and you'll probably go on to have a fine career without ever having touched the stuff.

In my experience, sometimes. Not that often, depends on the task.

The benefit is I can keep some things ticking over while I’m in meetings, to be honest.
