To be fair, the specific use case mentioned on the github is typing "shutdown -h now" into the wrong terminal window, and the way it's solved is quite clever: it asks you to enter the hostname of the system you're actually trying to shutdown. This is something that could conceivably happen to people who are properly trained. This also means it doesn't fall prey to the usual "do you really want to do this? yes - no" prompt, where you just get used to automatically hitting "yes." Even if you habitually enter the hostname, it'll be wrong if you execute the command in the wrong terminal. |

But as an idiot, I’m here to tell you it isn’t idiot proof. In a moment of suboptimal attention, I could easily ask myself “What host am I on?” rather than the more appropriate question “What host am I trying to shutdown?”
In my case it may be quite a bit worse because I have hostnames in PS1 specifically to avoid running any command on the wrong host. With the hostname right in front of me I could easily accidentally habitualize just typing the hostname I see.
Over time, I imagine this would befome more likely rather than less, so although I think it probably helps, I am sympathetic to GP’s view of futility.
