>A lot of tech people tend to forget that for most people, a computer is not an end unto itself. It's just another tool for getting their real work done. Why "advocate" a desktop if people can get their work done on a tablet or phone? A desktop system has a lot of complexity that, for most people, probably tends to get in the way of actually getting their work done as much as it helps them.
Tablets and phones are consumption devices, not creation devices. They are a hideously bad match for trying to do any sort of serious development work, or even your bog standard PowerPoint deck. A Surface is about as tablet-y as you can get while still being able to do reasonable work, but a Surface is still a real computer under the hood. Anyone who works with touch-only systems could probably give you a long list of design decisions that slow them down when trying to do anything serious.
>I'd argue that very few people's productivity is measured in how efficient their file operations are. It's sort of like believing you're going to be vastly more efficient as a programmer if you memorize a bunch of keyboard shortcuts or type 60wpm instead of 30. Unlike the movies, programming isn't about how fast you type.
I think his point isn't just doing file operations, but rather that everything from the CLI is going to be faster and more powerful than a GUI when you know what you're doing. GUIs are great when doing graphical stuff, but for text-based work, text-based interfaces work better. UNIX is an operating system that is also an integrated development environment.
And typing fast really does make a difference. I mean, sure, Amdahl's Law and everything, but when you know what you're going to do, your typing speed will linearly translate into productivity.
