What is machine learning, and what does it mean for music?

As the name implies, machine learning is a form of AI whereby a computer algorithm analyses and stores data over time, then uses this data to make decisions and predict future outcomes. Deep learning is the next evolution of this: instead of requiring human'supervision', algorithms can autonomously use'neural networks' analogous to the human brain. Put simply, lines of computer code can now, to some extent, be programmed to learn for themselves, then use those learnings to perform complex operations on a scale that far surpasses human abilities. Considered the single biggest advancement in software development over the past few years, this technology is possible thanks to revolutionary advancements in computing power and data storage, and is now an integral part of day-to-day life, like how Siri or Alexa intelligently store data to predict future actions. Ever wondered why Facebook's'People You May Know' and those pesky suggested ads on social media are always so accurate?
