Apple stresses user privacy to a greater degree than Google, which offers free and ad-supported services with the understanding that Google might use your data to improve its technology.
Jeff Dean, co-founder of leading AI research lab Google Brain, will now be in charge of Google's AI team.
It should be noted that engineers with AI expertise are highly sought after in Silicon Valley, and Apple has made a number of high profile hirings of late in the AI field.
