They're likely to remain useful in some contexts for quite some time.

A few really good planes and a lot of low-end drones is probably what we'll have in a few decades.

In particular the F-47 is expected to act as a forward control node for drones. We're probably decades away from having AI software that can autonomously execute any type of complex mission. So that means there's a critical need for a crewed aircraft survivable enough to get close to the target, even if it doesn't have to directly employ weapons itself.

The USAF requires a very high-end fighter with a range of several thousand nautical miles (or at least double that of the F-22) in order to operate within the area denial bubble of China, which they project is only going to get more and more capable.

Thats interesting - am I understanding correctly that the reasoning is that forward air bases will become more vulnerable, so we need to be able to operate from domestic bases?
