So i got a prusa 3D printer, its loaded with computer chips, my pc is to old to operate any functions or even flash the system. Yet a lathe and mill maufactured 50 years ago still work fine. Is this really the way of the future? How can we advance if we spend every moment trying to catch up old systems to new systems or replacing those systems entirely? I would think investment means return, my newest investment requires further investment but will also become obsolete and thus worthless. Compatability should not be an issue when moving electrons or operating systems built on the same system of 101010101010101010100001000111001101010001111001. To conclude i need help with understanding the pixies in my magic box. Takers?
