They should work on improving the reliability of the aircraft. Instead they are still cramming more crap in. Block 4.
Which is likely to make the reliability even worse.
I think pre-B4 will be scavenged, retired early or passed down to "lesser/less friendly allies" by around 2035. It's not worthwhile, there's just too much hassle in maintaining them when they won't even have Block 4+ capabilities.No one wants to make bug-fixes or pay off technical debt after all. It's far more sexy to showcase new features instead!
I never thought I'd be able to draw a parallel between fighter aircraft and software. :facepalm:
