Thank You for warm words, I'm electronics dev by first education. But, I must admit, in modern tech, each day larger share get software. For example, because of sanctions, Russians have troubles in buy industrial chips for automobiles, and their govt decided, to accept manufacture new autos without modern safety systems - no airbags, no abs, no esc, etc. Military jet planes are now micro datacenters, for example, F-35 just have few racks with triple redundant computers, because they are nearly impossible to fly without software; similar thing with Russian Su-27 and all their relatives (Su-33, Su-35) - to be more maneuverable, they designed to be extremely unstable, so software constantly correct their air-dynamic configuration, also their air-dynamic configuration automatically change with speed change. If You prefer numbers, from ~ F-16, about half cost of military jet plane is software.
