I like the diff idea for many things in government data. But the real physical world has much higher costs, ask the hardware manufacturer that makes a chip that is not bought. Software has much easier iteration properties. Hardware and physical changes or slow changing society/process changes are much much harder to iterate. It is like writing code on punch cards or having to make the entire computer. I think there is a fair amount of experimentation, trial and error and more in healthcare mainly private but also public. What we are seeing in congress is what we all deal with individually and as group, it is just freaking hard to get teams to agree on even a direction on touchy subjects and the larger they get the harder it is. Resistance to change and posturing prevents faster change, mainly because of that error side of trial and error and large doses of groupthink. We can't easily roll back changes in law, process, society as you can in software. But I agree it is so bad right now we have to do some changes to see what happens.
