fax machines are obsolete because the newer techs are more convienient, in just the same way that not having to worry about type in a loosely typed language is more convienient than having to worry about it in a strictly typed language.

that doesn't mean that we won't ever need fax again, or morse code, it still exists and has it's place, but for the majority of users it's not needed, and the same will happen with all technology, including programming. eventually almost noone will need or use something low level like C, just like most people right now don't need or use assembly, or even lower level, machine code, or even lower level... I don't even know what's lower level. Point being as things move along the lower level, while still being there, is understood and used by less and less people.
