raj rajkumar of carnegie mellon university. carnegie mellon is the birthplace of self-driving car technology. thanks in large part to the work of raj and his colleagues. they've been the leading innovators in this field for more than 25 years. so how does his self-driving car make decisions to safely navigatehe world like a human driver? should we get started? pretty eager. - yes, we can. - since raj is distracted by our conversation, for safety reasons, the state of pennsylvania requires another driver in the front seat to monitor the road. this is so cool. i'm nervous but excited. what's the longest you've ever driven a vehicle, autonomously? - we have gone hundreds of miles. - [shivani] awesome. - i'm going to go auto by pressing this button. - oh my gosh (laughs). it really is driving itself. while most self-driving cars are built from the ground up, raj just bought a regular used car and hacked it with powerful onboard computer systems, making it more adaptable than other regular cars. - we've installed a bunch of sensors i

me now to discuss, michael smith, professor of information technology and marketing at carnegie mellon universityhael, this seems to be part and parcel of a larger rethinking of the original idea of the open internet this idea, oh, well, you know, i'll look cookies follow me around, and i'll get advertised to that means i get information for free, and well, you know, sites can post stuff, that's going to lead to open debate which is going to make society better or not, right? >> exactly i think one of the things we need to recognize with section 230 is what we're trying to do is balance the needs of platforms to not be held immediately responsible for what gets posted to their platform, and also provide platforms with the proper incentives to police their site against known harmful content. the question is whether we got that balance right in 1996 and i think you could make a very good argument that we might want to rebalance that. >> what does rebalancing look like, perhaps short of just getting rid of section 230 all together if that happens, certain services just won't be able to operate witho

researchers at carnegie mellon university of designed a system called re skin. it enables robots to differentiate between objects such as thin layers of cloth. to fold laundry . the robots used a sensor to mimic the way humans can feel the top layer of a towel or shirt. the researchers say. they didn't teach the robot how or where to grab the fabric. instead they taught it how many layers of fabric it was grabbing . so welcome to the nine. so you're gonna have your washing machine, your drying machine and then the other tool you'll have in the future is your robot laundry folder? so you know if you so explain to me this i think in the future and sometimes i try to, you know, predict what's going to be happening. i think in the future you're not going to have to take the look the wet laundry out of one machine and move it. because you know that's something right . you know, like, okay, it's not a pain. it's just like you would think that someone would have figured that out. right they have a lot. they have washing machines that that that's all in one, so it'll wa
