Pilots really push back against this kind of safety feature. They want 100% control of their vehicles, including the ability to lift the landing gear while on the ground, because the risk of equipment failure that cannot be manually overridden is high.
There's a limit to db, something like 190, where the noise creates a vacuum followed by a blast wave, followed by a vacuum and so on.
Get something that makes that kind of noise next to a fire, then something on the other side of the noise (away from the fire) that either dampens or cancels the noise travelling away from the fire, and they might be onto something.
I'd agree easily that China and India are at least a big of a threat to the US position as top economy. There's nothing, other than inertia and maybe cultural influences, maintaining the status quo. I say maybe, because I don't know a lot about Indian and Chinese culture.
I feel that there's not a lot of concern here about the possibility of falling behind, because we're all entertained to a degree where we just don't care. So many people are always entertained by television, radio, music, sports, infotainment, and as a result they barely take their education, families, and work seriously, let alone global balance.
If we lost the 24/7 entertainment, we'd see a shift in perception and an increase in competitiveness and motivation.
