stories tell that what happens deep within computers is composed of nothing more than 1s and 0s.

but what are these binary digits made of? voltages? electric charges?
are they actually digits? are they actually binary? at what level of abstraction?

or more importantly, maybe: of what else can these binary digits be made of?

to what extent can we compute without summoning, and/or depending on, the semiconductor industry?
its achievements are amazing, i agree.
but also, can't be really sustained.

let's play, let's explore possibilities.
maybe it's not practical today, but it can be fun.
it might be able to survive.

68 65 6c 6c 6f in hexadecimal,
01101000 01100101 01101100 01101100 01101111 in binary,
that in ascii,
encode hello.

shared as a photo, a "binary file",
traversing earth and sea,
yes, as electronic pulses via silicon and more.
