Stonemason, I take it that your analogy relates to deep sea oil exploration being an obsolete practice no longer required due to the abundance of shale oil and galloping progress of electric car technology. If I am correct in my assumption I agree that such a proposition is tempting and looks to have merit, however this is going to take time. One also has to remember that the future of Matrix Composite materials and their application to a myriad of other uses is promising to say the least. Its true, there is a storm to be weathered but if they are the "last man standing", which is a distinct possibility, they will have a monopoly in an area of technology for which the barriers to entry are substantial and the future looks bright.
