The world wouldn't end without computers either, or in fact, without humans, so this is a moot point... :) As I mentioned in the article, you can get away with working directly in sRGB in some cases (general image processing, non-photorealistic rendering), but in some other cases it's a must (physically accurate photorealistic rendering). But ignoring it will always produce wrong results. You actually might like those results, but the important point I was trying to get through was to be aware of these potential issues, and then you may ignore them at your own peril.
