Lately I have been noticing a lot of things changing from mechanical to electronical. Take boilers for example. Before, they had mechanical arms controlling how much air and gas would be used when they are firing. These linkages would stay good forever as long as you oiled and greased them, and didnt move them out of their original position. Now, barely anyone knows how to work on them and adjust them to work. So....comes in the electronical equipment. No more mechanical linkages, just parts talking to each other. Which can be more accurate. But that brings me to the issue, if that company doesnt come to service them, and their programming starts to have bugs...only they can fix it. You are forever tied to that company now. Which I dont feel is a great idea, I would have rather fixed the mechanical linkages. Anything like this happen to you lately?
