It sometimes happens that I come upon a post where a completely ridiculous answer is accepted by a clueless poster.
The immediate gut-response is to do something, since leaving the situation as-is is an affront to SU. But there is nothing to do. I cannot flag the answer, since there is no flag for "Answer cannot be accepted". Down-voting the answer will only let off steam, but will not correct the situation.
As an example take the post How exactly does ROM work when the power is turned off?
The accepted answer cites an ancient technology from the 1960s or 70s, before ROM ever existed. It pretends that there are little physical wires running inside the ROM, representing bits, which are connected or disconnected to denote 0 or 1.
My attempt to explain that ROM uses such newfangled concepts as solid-state technology and electrical charges, has met with total incomprehension.
Is there anything else to do than shake my head and forget about it?
