00:01:56.159 --> 00:01:58.880 worried about is getting more dopamine 00:01:57.840 --> 00:02:01.360 off of social media 00:01:58.880 --> 00:02:02.000 that's right what are the consequences 00:02:01.360 --> 00:02:05.520 of us 00:02:02.000 --> 00:02:09.280 being addicted to social media instagram 00:02:05.520 --> 00:02:11.280 twitter texting snap what is the worst 00:02:09.280 --> 00:02:12.640 long-term consequences we could face 00:02:11.280 --> 00:02:14.560 with this well 00:02:12.640 --> 00:02:15.760 how about the end of the human race you 00:02:14.560 --> 00:02:18.800 think so yes 00:02:15.760 --> 00:02:21.200 tell me why we've got so much amazing 00:02:18.800 --> 00:02:22.239 cool stuff we've got all kinds of things 00:02:21.200 --> 00:02:23.920 we can buy 00:02:22.239 --> 00:02:25.680 we've got all kinds of things we can 00:02:23.920 --> 00:02:28.080 experience 00:02:25.680 --> 00:02:30.800 something's got to give what is it that 00:02:28.080 --> 00:02:34.239 we're giving up for all of these things 00:02:30.800 --> 00:02:36.400 the answer is children once an economy 00:02:34.239 --> 00:02:38.560 reaches a certain point of prosperity 00:02:36.400 --> 00:02:40.640 the members of that economy lose 00:02:38.560 --> 00:02:42.959 interest in reproducing 00:02:40.640 --> 00:02:45.360 all of the developed nations have a 00:02:42.959 --> 00:02:47.760 negative population growth rate 00:02:45.360 --> 00:02:49.440 in order to keep the human race going 00:02:47.760 --> 00:02:52.720 each woman needs to have 00:02:49.440 --> 00:02:55.440 2.1 children two children to 00:02:52.720 --> 00:02:56.160 replace her and the father and one to 00:02:55.440 --> 00:02:58.400 replace 00:02:56.160 --> 00:03:00.159 people who die before they have a chance 00:02:58.400 --> 00:03:01.920 to reproduce 00:03:00.159 --> 00:03:04.720 in all developed countries the birth 00:03:01.920 --> 00:03:07.040 rate is less than 2.1 percent 00:03:04.720 --> 00:03:08.319 even in developing nations uh we're 00:03:07.040 --> 00:03:10.800 seeing this happen 00:03:08.319 --> 00:03:12.560 uh it's falling and falling and falling 00:03:10.800 --> 00:03:14.080 we don't have a solution there are some 00:03:12.560 --> 00:03:14.720 countries where they're not paying 00:03:14.080 --> 00:03:17.120 people 00:03:14.720 --> 00:03:18.720 to have children and even that's not 00:03:17.120 --> 00:03:21.760 working as we get 00:03:18.720 --> 00:03:22.640 more and more gadgets that attract our 00:03:21.760 --> 00:03:26.159 attention 00:03:22.640 --> 00:03:28.239 they become substitutes for family 00:03:26.159 --> 00:03:29.760 and ultimately the human race is simply 00:03:28.239 --> 00:03:32.239 going to collapse unless something 00:03:29.760 --> 00:03:32.239 changes
