That’s not to say you’re crazy or anything. You do you. But do understand that you almost certainly constitute a nearly irrelevant minority of users of homebrew.
Intel homebrew is larger than Linuxbrew, yet I think it'd be shocking if they dropped support for Linuxbrew.
Old machines still work. They're still deeply useful. I'm still using daily an Intel Macbook with homebrew on it. When I no longer use it daily in some years more, it'll still make a perfect server.
