What Kate said except I'm pretty sure it's not actual biological neural nets, it's hardware that's designed for artificial neural nets.

It is not AI hardware but neuronal nets. That type of hardware can be used to "recognise" music, speech, imagery, patterns in general, like e.g. fingerprints and your voice, so it makes possible to e.g. activate your phone by your fingerprint or voice.

The AI can replace biased knowledge.
