A firewall’s purpose is very simple: to block or filter people from accessing your computer remotely or viruses and worms infecting your machine.

Most people did not consider the power that the home computer represented and they found it as useful as a normal calculator. And that really makes sense. If all you were using your computer for at the time was to keep the budget of your household and organize recipes then you would probably think of it that way as well.
