The danger you have, as the French discovered 10 years ago when they went to an integrated telephone system that was very advanced for the period, is that if you go to the best available technology while you're in the early stages of a technological revolution you get an enormous capital investment that's obsolete. Building canals in the 1830s, which rapidly was obsolesced by the railroads. I think it would be more likely to evolve very, very rapidly through that kind of free-standing decentralized model than we are from a centrally governed planned effort to brute force the current technology. My guess and my hunch is that it's at least two generations too early. My hunch is that there's a pretty high chance that its sensor system and its database system will turn out to be far too centralized and far too controlling for where we're going.
Space is cheaper than land.
Whereas a space-based system gives the pilot more control. The power struggle is over who's in charge, and I'm very leery anytime public bureaucrats explain why they should allocate the money to buy what they think is the state of the art, because as a general rule you can already find crazed experts who know the next-generation's breakthroughs before they start laying the concrete for the current generation. That's also, by the way, why I like decentralized marketplaces, because you can obsolesce things and just let them go bankrupt. Highly centralized control system of Mastercard. I have a machine on this bridge, and so you have your car that permanently has this decal and you can go through any of these data systems in this country.
