David Autor: Why are there still so many jobs?

18:37 minutes · Filmed Sep 2016 · Posted Dec 2016 · TEDxCambridge

Here's a paradox you don't hear about: Though machines and computers are constantly being created to do human jobs, the proportion of adults in the US with a job has consistently gone up for the past 125 years. Which begs the question: Why hasn't human labor become redundant and our skills obsolete? In this talk about the future of work, economist David Autor takes on the question of why there are still so many jobs -- and comes up with a surprising, hopeful answer.

But Rabbi Sharon Brous believes we can reinvent religion to meet the needs of modern life.

Quote of the Week

It's foolish to say there's nothing to worry about. Clearly we can get this wrong. But it's equally foolish to say that our fates are sealed. That's not decided by the machines. It's not even decided by the market. It's decided by us."

Jia Jiang: What I learned from 100 days of rejection

15:31 minutes · Filmed May 2015 · Posted Dec 2016 · TEDxMtHood

Jia Jiang goes boldly toward something many of us fear: rejection. By seeking out rejection for 100 days -- from asking a stranger for a $100 loan, to requesting a "burger refill" at a fast food place -- Jiang desensitized himself to the pain and shame that rejection can bring and, in the process, discovered something powerful: Simply asking for what you want can open up new possibilities.

Our lives depend on a world we can't see: the satellites we use every day for communication, entertainment, navigation and so much more. But when satellites get old, break down, or run out of fuel, they turn into "space junk," drifting listlessly around the planet, endangering other spacecraft. Natalie Panek explains how our satellite ecosystem works -- and offers an idea of what we should do with our space junk. Watch »

Quote of the Week

To me, education is what people do to you, and learning is what you do to yourself. [School] feels like they're trying to make you memorize the whole encyclopedia before they let you go out and play ... like they assume you're going to be on top of some mountain all by yourself with a number 2 pencil trying to figure out what to do, when in fact you're always going to be connected, you're always going to have friends, and you can pull Wikipedia up whenever you need it, and what you need to learn is how to learn."
