While a human driver was still required for busy city traffic, the driverless truck completed a 120-mile stretch of highway without a driver in the front seat. It's not going to happen tomorrow or even next year, but sometime in the not too far future driverless technology is going to severely disrupt the transportation industry.
While neural nets are generally not meant to be great at cryptography, the experiment had some interesting results but neural nets are still far from the sophistication of human-made encryption methods.
Initially, the neural nets were fairly poor at sending secret messages. But as they got more practice, Alice slowly developed her own encryption strategy, and Bob worked out how to decrypt it.
After the scenario had been played out 15,000 times, Bob was able to convert Alice’s cipher text message back into plain text, while Eve could guess just 8 of the 16 bits forming the message. As each bit was just a 1 or a 0, that is the same success rate you would expect from pure chance.
