When Microsoft, Apple, Dell, Intel and co can produce affordable software and hardware that never crashes, I'll give it a thought. But even then human frailties will remain part of the equation in the design, construction, programming and maintenance of the control systems and infrastructure. All great stuff as aids and tools, but I'd struggle to rely on it implicitly. Most commercial aircraft can take off, fly and land at most airports completely automatically because each aircraft has millions of pounds worth of technology onboard. Would you happily be a passenger in one without at least one pilot? How about a car that only has a few hundred pounds worth of technology?
