Fic writers aren’t machines, but if readers insist on thinking of them in that way, then I will make things simple.
What would happen if you didn’t charge your smart phone, tablet, computer, gaming device, etc.
They would die and stop working and your hours of joy and entertainment would be gone.
But if you charge them up or plug them in, the fun can continue.
So if you must continue to think of fic writers as machines, treat them like you would your electronics. Make sure they are charged with lovely and thoughtful feedback. When they get overheated, let them cool down for a couple of days.
If you treat your favorite fic writers with care and respect, and give them feedback or kind words, they will be inspired and feel functional and they will continue to put out new content that you can enjoy for hours on end.
But if you throw them against the wall, let them get overheated, or leave them unplugged, the fics will die, and everyone will be sad.
