...The importance of governments in driving a nation’s scientific and technological achievements were outlined most clearly in the 2013 book The Entrepreneurial State by Mariana Mazzucato of Sussex university. In it, Prof Mazzucato traced the role the US government had played in creating Apple’s iPhone.

Without undermining the creative genius of Steve Jobs or the supply chain mastery of his successor Tim Cook, Prof Mazzucato found that almost every piece of technology in the ubiquitous smartphone had its origin in a government programme, dispelling the myth that the success of Silicon Valley was largely the work of eccentric entrepreneurs tinkering in their garages and savvy investments made by venture capitalists.

Apple’s voice-activated personal assistant software Siri, the microprocessor and the micro hard-drive all had their origins in research by the Defense Advanced Research Projects Agency (Darpa), run by the Department of Defense; the multi-touch screen was developed by the CIA and Darpa; GPS, found on most smartphones, was a technology originally created by Darpa and the US Navy. It was the patient investment of government that made today’s digital revolution reality. Prof Mazzucato says: “In almost every sector from IT to biotech, nano tech and clean tech, it has been the US government that has led the way investing in key areas across the innovation chain.” ...

If you look at “gaming” keyboards, a lot of them sell for $100 or more on the promise that they’re fast.
...
Despite all of these claims, I can only find one person who’s publicly benchmarked keyboard latency and they only tested two keyboards. In general, my belief is that if someone makes performance claims without benchmarks, the claims probably aren’t true, just like how code that isn’t tested (or otherwise verified) should be assumed broken.
...
A year ago, if you’d asked me if I was going to build a custom setup to measure keyboard latency, I would have said that’s silly, and yet here I am, measuring keyboard latency with a logic analyzer.
