Regular duties such as patrol could be taken over by simpler planes with lower maintenance costs where the full capabilities of a modern fighter are not required.
Instead, those things would probably have massive endurance, I imagine.
The problem with stealth aircraft isn't finding a missile that can hit them. It's getting a reliable, targetable lock on them. You can detect stealth aircraft with low frequency radar, but you get a very poor quality return. Low frequency doesn't just make stealth aircraft more visible, it makes *everything* in the atmosphere more visible, including water vapour.
You may need a visual or multispectral lock. Until the terminal phase, command guidance might be necessary. Not sure about all-weather use, though. High frequency radar from very a short distance?
Why do so many Americans get boners at the thought of nuking an entire nation into a parking lot?
I blame the American car culture.
