Most engineering problems, especially ones like this that are straight out materials / design problems, (as opposed to problems requireing the development of new technology) can be solved with a big enough budget. The only problem is that it's expensive, and consumers will only pay so much for a product. Especially products requiring high r&d effort, and low sales volume.
I'd say the reasons that bombers have problems with crowns (assuming they do, i don't know anything about that problem) is purely cost based.
And new technology is always appearing even for old processes. For example, metal casting has been around since man started working metal, and is one of the most basic metalworking processes we have, and yet just this year, some of the big japanese motorbike manufacturers have developed a new casting process that allows them to achieve much thinner wall thickness, and less casting defects than was previously possible, leading to increased stiffness and strength, with less weight. It's not directly applicable to the forks we're talking about it (although it has potential for monocoque frames), but it demonstrates that things are always advancing. This years bombers may snap, next years may not. You only have to look at the past to see that all the limits that people said would never be broken, have been, and easily. ("no bike will ever have more than 6in travel" anyone?".)
I think i must be up to about a dollar in 2c pieces tonight,
