One of the greats in computer science has a series of interesting quotes. https://www.azquotes.com/author/15849-Niklaus_Wirth
One I really like is: "The belief that complex systems require armies of designers and programmers is wrong. A system that is not understood in its entirety, or at least to a significant degree of detail by a single individual, should probably not be built." ~ Niklaus Wirth I often wonder if LinuxCNC has reached this point. Although so far, Andy Pugh appears to be that single individual so I may well be wrong.
