she's professor for ethics n i t at the university of handbook. and she also sits on the german ethics council . and it's a great honor to welcome a special guest, a pioneering researcher, who has been referred to as the father of modern a i. he's scientific director at the renowned a. i lab i. d. s. i a, you can submit to move our joins us virtually from switzerland. let me ask all of you to just give us a very quick take on how you see this balance between uh, between risks and benefits and the color of the scientists warning of possible extinction. compare a high to societal scale risk, such as pandemic send even nuclear war. would you agree? well, i think that's a little excise you're right, because the risk i see are more they come from everyday life. i say risk regarding employment. what are we going to do with people who is being displays the new information technology is isaac of risk because the information, whether it's through one, whether it's not through. when we read something on the internet, i see research regatta being isolation of

enhanced weathering release has nutrients that improve the soil. tobin almonds team at the university of handbook is investigating exactly how much c, o 2 is captured in the process. the result, the method works and not in, in the power train. as something it often say, it also works in that field. we have to assume that he only got on it's just more difficult to prove it doesn't. and of course of field is not in close, like a bucket or a tube or a huge rain barrel used for an experiment. kind of these things, it's open in all directions, upwards, downwards to all sides. so it's hard to really trace where the product of our weathering ended up the whole are. they still stuck in the ground ice? maybe we can't recognize them at 1st and what we spot them again later. that's the challenge. let's try to talk to them on is sure to look and keep catching up to 5 percent of the c o. 2 emitted annually worldwide. the infrastructure already exists, and there is plenty of arable land. but there's even more ocean. the oceans already excelled around a quarter of the carbon dioxide emissions. and research has

on asians, and secondly, not just to public universities but private ones as well, 72% of all four-year colleges, they have to rewrite the admission handbook. california banned race in admissions almost 30 years ago and tells us what could happen. california uses now 13 factors to judge who gets in, and who doesn't, from class rank and gpa to personal achievement. race is not one of those boxes. so, being when voters banned affirmative action, black and hispanic enrollment like ucla and berkeley fell by 40%. last year's am ning class, 3% black, 20% hispanic, less than half the statewide population figures. but 43% were asian, three times higher than the statewide population. experts say universities will adjust by using algorithms to compensate for race, looking at crime and poverty rates of the applicant's zip code, family income and education. >> if you look at the hundreds of other factors you can create something that will have the same effect of -- as affirmative action without even looking at race once and that's what i expect to see across all the elite private colleges. >> so here is a snapshot of where some of the top public unive
