You are still wasting a bit and you are really thinking in decimal,
not binary. Obviously you are new in the computer biz. I was around
when a bit cost about a hundred dollars. We didn't waste them.
2 bit slots (10) represents 4 states
0 = people who don't understand binary
1 = people who do understand binary
10 = people who think they understand binary
11 = people who don't give a shit anymore

You're thinking about states.
The original statement was about a number, the number of kinds of
people. 0 may be a state, but it doesn't represent a kind of people.
There are two (10) kinds of people, those who understand binary and
those who don't.
Who says? Maybe those are the ones who DO understand it.
My point is that if you want to create a new discussion, you can do
that. but the original discussion was about 10 (two) kinds of people,
not two states one of which could be zero. Zero is not a kind of
It's not funny to write there is one state (01) in addition to the
zero state, of people, the state of understanding and the state of not
understanding. That's not funny. It's not a joke.
Those who are arguing with you aren't doing so because they are they
are thinking in decimal but because they are thinking in humor.

Reading a core erased it so you had to have circuitry to rewrite it or
change it. You sent a pulse to flip it and then sensed whether it
flipped or not.
The cores are strung in a matrix with an X and Y wire going through
each one. If there is current on both wires, it will flip the core, if
it is only in one wire it will not flip. The material is carefully
selected to have a very high hysteresis so it will work that way.
