There is a trend to assume new technology will always replace old technology.
During the Vietnam war the F4 ditched its cannons for the sidewinder air to air missile.
The sidewinder is fire and forget for the most part and somewhat of a no brainer whereas cannons require more skill and training in dogfighting.
It also gave the US a MAJOR advantage (in theory) vs the MiG.
The problem is that the Vietnamese picked up on this and changed their tactics.
Before this the US had air superiority and a significantly higher kill ratio.
The Vietnamese built 'hidden' airfields and would dispatch their MiGs when the F4 was directly overhead and engage them in head to head dogfights.
The F4s needed to build distance to launch a sidewinder and this dramatically rebalanced the kill ratio and during this time it came out to close to 1:1 with the US having a slight advantage.
They US realized their mistake and subsequent F4s had cannons...
Same thing here with cars. When the new screens came out everything was done through software but it's just NOT a good design.
When I'm driving I want to push a button and be done. IF just for safety.
When the UI locks up or is slow it's literally a safety risk.
Wasn't another factor of the drop in head to head kills and then the subsequent improvement due to the energy-maneuverability of the fighter jets? John Boyd's biography (https://www.goodreads.com/book/show/38840.Boyd) talks a lot about his work while an instructor at the Air Force.
The vietnam era missiles were really bad missiles with a really bad pk. Lack of a cannon wasn't the problem, and adding one wasn't the solution. Fixing crappy missile technology was the solution.
I don't think there's been an air to air gun kill in four decades, maybe five (US at least). Essentially all air to air combat is with missiles, to the point two of the three JSF variants don't even have a built in cannon and will likely almost never fly with the gun pods they are building for them.
