Google CEO: A.I. is more important than fire or electricity

For its part, Google has committed to donating $1 billion to job-retraining over the next five years to help a transitioning workforce. But according to YouTube CEO Susan Wojcicki, it can't be the sole responsibility of the private sector -- companies and the government are going to need to work together, she says. Caution and strategic retraining are necessary because there is no way to stem the tsunami of technological innovation once, nor should there be, both Wojcicki and Pichai point out. "We have to recognize where we do live, in this time where there is really dramatic change from a technology standpoint and the innovations that we have, but that doesn't mean those innovations are going to stop," says Wojcicki. "Technology is going to continue, it is going to continue to move forward. You need to move forward with that technology responsibly."
