Sounds like the Pratik Arora isn’t listening to enjoyable podcast. I have found some where i enjoy the host, the topics (usually), and they don’t give too much or too little. I always find it weird when articles say “something dramatic will happen.... unless”
"Siri, the first virtual personal assistant, arose from decades of SRI research in artificial intelligence (AI). The technology was developed through the SRI-led Cognitive Assistant that Learns and Organizes (CALO) project within DARPA’s Personalized Assistant that Learns (PAL) program, the largest-known AI project in U.S. History, and joint work with EPFL, the Swiss institute of technology.
"SRI spun off Siri, Inc. in 2007 to bring the technology to consumers, raising $24 million in two rounds of financing.
"In April 2010, Apple acquired Siri, and in October 2011, Siri was unveiled as an integrated feature of the Apple iPhone 4S."
I don’t think it can be regulated. I believe it will develop into a black market (dark web). Most regulations in the American industry are usually for just profit or are crippling. Its hard to imagine internet regulation going well.
Is there a true app that, preferably open source, that can disable the all microphones, confidently, for all apps, without having to physically disable my microphone as Edward Snowden suggested?
Depends on the permissions model of the OS, and if you trust the OS. Hence why Edward Snowden and Bunnie Huang developed the Introspection Engine [1].
It’s reasonable to assume that if you can’t audit and review the code of the app and the OS, you can trust neither and need safeguards at lower levels of the stack.
Yes, they're called amplifiers. Directional coupling circuits would apply in theory, but not in practice; they're good enough to do full-duplex audio over two wires, but not nearly good enough to deal with the sensitivity of analog inputs if you want to prevent a signal from being read.
