Appearance in 20 years sound more reasonable than not appearing for the next 100 years.
To assume that since UCAVs crashes now they will therefore continue to crash is downright lame. Manned aircrafts crashes too.
The X47B/Phantom Ray are in a different league from the Avenger/Predator which are used to fight the Taliban.
To assume that the X47B/Phantom Ray will remain just that for the next 20 years is unreasonable. They will evolve.
These are not the years of the F22 where people code in Ada. When people had to design parts using a drafter. When the maximum computing prowess they can put inside the F22 is a cluster of i960MX and later PPC G5. Things moved on, people use Rapid prototyping tools, object oriented language, CAD/CAM etc for speeding up development. Today Intel processors(embedded options) are more than 1000x that of i960MX(a stone age ~66 MIPS) all within an envelop of 100W with passive heatsink, No fancy cooling needed, in a space of less than 300mm2. The computing power evolved exponentially.
Money is another thing, but if the necessity arises it will be done.
Sorry for derailing thread.
