And often the most useful software is closed source proprietary things that cost money to be used effectively. That hasn't stopped open source from building impressive and useable systems that are serviceable enough for most use cases. You can't fork photoshop, but GIMP (for all its warts) exists and you can use it for photo manipulation. You can't fork Solidworks, but FreeCAD and OpenSCAD exist, and you can use them to do 3d modeling. You can't fork Eagle, but KiCad exists and you can design your own PCBs with it. You can't fork Windows or MacOS but Linux and BSD exist and they probably already run most of your hardware. You can't fork Oracle, but Postgres and MariaDB exist and you can run a business on them. Unless we stupidly legally lock AI training and model creation to massive proprietary corporations, why do you think the same won't hold true for open AI models and projects? Maybe Claude will always be a better code agent than AInix or whatever, but as long as AInix is good enough, that doesn't matter any more than it matters that Solidworks is better than FreeCAD.
