> Well that would be inefficient. For each command you run the kernel has to read the file, detect that it has a shebang, parse the shebang line, and then finally load the actual executable in memory. Those that exist today would, but no kernel would have to work like that. Once you've agreed that monolithic kernels have merits, you've accepted that the kernel can do whatever it wants to make this efficient—including being complicit in this scheme and leapfrogging over most of what you just described.

> Those that exist today would, but no kernel would have to work like that. That's a pretty weird argument. "Yes, what you say is completely correct, but let's imagine a world where you were wrong." We have what we have, today. We should form conclusions and make decisions based on things that exist, not on things that we might dream up.

I'd say "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize" covers this case pretty squarely (from <https://news.ycombinator.com/item?id=15892014#15893789 https://news.ycombinator.com/item?id=15892014#15893789>) See also: <https://news.ycombinator.com/item?id=38688831#38690517 https://news.ycombinator.com/item?id=38688831#38690517> plus lots (and lots) more.
