[Jason Bourne] How is Bourne able to continuously foil the CIA even though his training becomes more and more obsolete and he's missed out on an entire decade's worth of advances in spycraft?

Every time the CIA has set out to find Jason Bourne, they've succeeded. He's a ghost, but as you say he's a largely obsolete ghost - even in the first film, where two separate Treadstone assets are able to locate him.

The problem is, once they've located him they still have to actually capture or kill him - and the technology for that hasn't really progressed beyond guns, tasers, and burly men with a talent for brutality. Jason Bourne is very good at dealing with those things.

After the events of the third film, Bourne was missing, presumed dead. If they'd decided to search for him the CIA would probably have found him again, but going after Bourne had ended a lot of careers. Simpler to just accept that he's dead, and focus on active threats.
