Nothing beats seeing TED talks live, and me going this year was no exception. The Pope, Tim Ferriss and Elon Musk all did fascinating talks, and others explored stress, physical limitations and the business of art. For all the fanfare, though, only a handful of talks are actually put online.

A month after TED 2017, a few great talks are now watchable for free. Here are ones you should watch immediately.

Killer quote: Machines have calculations. We have understanding. Machines have instructions. We have purpose. Machines have objectivity. We have passion. We should not worry about what our machines can do today. Instead, we should worry about what they still cannot do today, because we will need the help of the new, intelligent machines to turn our grandest dreams into reality.

Killer quote: Two years of independent evaluations tell us that our kids eliminate the summer learning loss and make growth of one month in math and two months in reading. So instead of returning to school in the fall three months behind, they now go back four months ahead in math and five months ahead in reading...What's even more exciting is that if we can prevent five months of lost time just by redesigning two months, imagine the possibilities that we can unlock by tackling the rest of the calendar year.

Killer quote: What we're left with here is this inevitable cliche: "Those who don't study history are destined to repeat it." What we have here is the opposite of it. Those who don't study the history of extraordinary human change, those who don't study the biology of what can transform us from our worst to our best behaviors, those who don't do this are destined not to be able to repeat these incandescent, magnificent moments.

Killer quote: All the books of knowledge that you might read and then go ahead and impart your knowledge through innovation, through creativity, through technology, but mankind will never be the wiser about its future unless it is coupled with a sense of love and compassion for their fellow beings... So I truly believe the future "you" has to be a you that loves. Otherwise it will cease to flourish. It will perish in its own self-absorption.
