Something I've always wondered about: why/how were fax machines possible so much earlier than scanners?I would have (naively) thought that, if you can make a digital representation of a document, transmit that representation through a phone line, and then print that representation back to paper, than you would necessarily be able to take a digital representation and save it to a hard disk. Why did that take years more to happen?(My guesses are disk space or display tech, but really curious)

@codesections I thought it was an analog form being sent over the phone line at first?

@codesections my understanding of fax is that the first fax machines were actually analog. They transmitted a signal that represented the scanned brightness, but they weren't truly digital until later.
