Computer literacy is on its way down, not that it was particularly high in the first place, so it's foolhardy to just assume some random Joe would know what a computer is, let alone RAM, let alone channels.
Yes. That is a programmer with literally no knowledge of what a computer is or how it works, even at a very rudimentary level.
Ever since I've been careful to never assume anyone knows anything about computers until they demonstrate otherwise, even in a seemingly techy place like HN.
Perhaps it depends on your definition of "Copmuter literacy", but do you have any evidence to back up that claim? I find it surprising.
