New in Git: switch and restore

if "the issue at hand" is the more typical modern work environment for devleopers, then no, I don't think he has much special insight. Indeed, the fact that he's wrangling something so large and important means he's unlikely to have the time and attention to devote a lot of thought to how best to serve a pretty different group of people.

An obvious consequence of this is git's terrible interface. Its premise is "if you totally understand what Git is up to under the hood, the interface is great!" Fine for a small in-group of kernel developers whose lives are distributed patch sets, but terrible for the average developer. It has taken 15 years to get some reasonably named commands for common things like "restore a file". That's a great sign that we shouldn't listen to Torvalds on topics outside the realm of his admittedly impressive expertise.

The rest I do on the command line because I don’t want to forget — except commits because I’m not at risk of forgetting “git commit -m”.

Linux is, very intentionally, a piece of software which does not have "easy to understand for non-experts" in its design goals. You generally interface through Linux with system call wrappers provided by a libc (or another specialist library for other interfaces like libfuse or libnetfilter or whatever), not directly. Linus is, quite obviously, good at many things; it's silly to assume that means he's an expert at everything.

Linus developed Git as a low-level tool. Linus put a lot of thought and care into getting the implementation details right, but intentionally did not build an easy-to-use interface. The Git command line that people use today ultimately derives from Cogito, a toolkit written by someone not Linus that sat on top of Git. Eventually Git (which Linus had long since handed off to someone else) adopted most of the conventions of Cogito and created a "porcelain"/"plumbing" split. If you think it was arrogant to develop Cogito, I suspect you disagree with Linus.

Finally, Linus develops Linux with a very particular model, with e-mail-based patch reviews, merges from subsystem maintainers, etc. Most projects (even most open-source projects, but certainly almost all proprietary projects) do not work this way. The Linux kernel does not use a GitHub-style workflow for development, which is by far the most common way people outside the kernel community use Git. It may well be the case that a lot of thought was put into making Git work really well for Linus's use case but it does not match how other people do development.

From the article, I was thinking that it was again a stupid confusing design for the cli to requires the -- even with a dedicated command.

One main issue with git is to not be consistent and logic with the comments. Always to use different way or option abbreviation for different command. For example having a space or a slash between repo and a branch in a command.

A much better response would be, "Thanks for pointing that out! I have filed an issue." One can't simultaneously through shade for not being community-spirited while expecting other people to do all the work.
