The Future of air warfare?

Where do you all think it will go? [Timrframe of say, 30-40 years]

For instance, a bare-bone short list of possibilities:

1. All combat operations performed by UCAVs piloted from safe locations, with secure uplinks.

2. All combat operations performed by UCAVs using autonomous software.

3. DEWs on large aircraft [such as a refitted B-52, or 777 etc] which is more akin to the protective bubble formed by AEGIS missile destroyers/cruisers around a carrier.

4. Widespread use of anti-satellite weaponary [be they lasers or conventional kinetic weapons] which reduce effectiveness of GPS and thus alot of guidance systems.

5. Hypersonic space-skimming bombers.

6. Development of DEWs to the point where all atmospheric based “air-warfare” is obsolete as its suicidal, hence into space warfare.
