how much lathe-ing have you done recently? did you load files onto your CNC lathe with an SD card, and thus there is a computer, which needs updates, or are you thinking of a lathe that is a motor and a rubber band, and nothing else, from, like, high school woodshop?
I bought a 3d printer years ago then let it sit collecting dust for like 2 or more years because I was intimidated by it. Finally started using it and was blown away how useful it has been to me. Then a long time later realized holy shit there are updates and upgrades one can easily do. I can add a camera and control everything and monitor everything from any online connected device. I always hated pulling out the sd card and bringing it to my computer and copying it over and back to the printer and so on. Being online makes things so much easier and faster. I have been rocking my basic printer for a few years now and have not paid much attention to the scene and then started seeing these multi color prints holy shit am I slow and behind the times. The newer printers are pretty rad but I will give props to my Anycubic Mega it has been a work horse and I have had very little problems. I don't want it to die on me but a newer printer would be cool also.
There are immense benefits to using modern computing power, including both onboard and remote functionality. The cost of increased software security vulnerability is easily justified.
