00:00:00.000 --> 00:00:05.279
one of the most irritating things about modern life you know other than

00:00:03.280 --> 00:00:07.839
political polarization stagnating wages and the feeling of somehow being

00:00:06.400 --> 00:00:12.080
socially isolated in a hyperconnected environment is how difficult these

00:00:10.400 --> 00:00:15.839
stupid little capture puzzles have gotten but why is this happening a while

00:00:14.320 --> 00:00:19.840
ago we did an episode on those super simple i'm not a robot recaptchas and

00:00:18.000 --> 00:00:24.160
those aren't that bad you just click a box and that's it but now it seems like

00:00:22.400 --> 00:00:29.359
we're having to solve these arcane picture puzzles sometimes multiple times

00:00:26.960 --> 00:00:33.360
simply to read a news article so what gives well part of it is that the

00:00:31.279 --> 00:00:38.239
evolution of captchas to become more annoying is part of an ongoing arms race

00:00:35.760 --> 00:00:42.320
between spam malware and shopping bots on the one side and cloud and website

00:00:40.320 --> 00:00:46.719
operators trying to stop them on the other back in the day bots were so dumb

00:00:44.480 --> 00:00:50.320
that just a slightly distorted word or two could send them packing but of

00:00:48.480 --> 00:00:53.840
course it was quite easy for fleshy humans to understand what was on the

00:00:51.840 --> 00:00:58.399
screen but unsurprisingly there's been a lot of investment over the past couple

00:00:55.440 --> 00:01:03.680
decades into automated optical character recognition or ocr which helps digitize

00:01:01.600 --> 00:01:07.920
old books and other publications so that they're more easily searchable doing

00:01:05.439 --> 00:01:12.080
this requires ais to discern text even if it's distorted in some way so over

00:01:10.159 --> 00:01:16.320
the years efforts were made to make them better at this and unsurprisingly the

00:01:14.240 --> 00:01:22.799
text we put into those little captcha tests helped the ais do this many captchas use

00:01:20.080 --> 00:01:28.640
scans of distorted words from real books or newspapers and because we humans took

00:01:25.920 --> 00:01:33.200
so many of these tests we trained ais to become very good at them but

00:01:30.720 --> 00:01:37.520
unfortunately ai algorithms can be used by bots so we stopped using word-based

00:01:35.360 --> 00:01:41.759
captures and moved on to those little picture puzzles which i'll complain

00:01:39.439 --> 00:01:46.560
about more after this message from our sponsor jackery jackery's explorer 1500

00:01:44.479 --> 00:01:50.640
portable power station has enough juice to keep all your devices powered and

00:01:48.159 --> 00:01:55.200
connected it's huge 1500 watt hour capacity and 1800 watt output rate

00:01:53.040 --> 00:01:59.520
allows up to seven devices plugged in simultaneously and it takes only four

the link below and get 10 off with the code Linus tech tips for a while picture

00:02:06.719 --> 00:02:12.640
captures proved more effective than word captures but guess what

00:02:10.720 --> 00:02:17.760
google who's responsible for producing many of those picture puzzles uses human

00:02:14.879 --> 00:02:20.080
input on those to train their ais as well

00:02:18.560 --> 00:02:23.920
if you've noticed how lots of these captures are photos of street signs

00:02:21.920 --> 00:02:28.000
traffic lights and crosswalks etc it's because google is taking all

00:02:26.400 --> 00:02:33.280
that data that you give it when solving these puzzles and using that information

00:02:30.160 --> 00:02:35.040
to help build ais for self-driving cars

00:02:33.280 --> 00:02:40.160
as well as to improve the quality of results on google maps and again ai's

00:02:38.160 --> 00:02:44.239
got really good at solving these puzzles so the folks behind captcha have been

00:02:42.080 --> 00:02:48.800
making them progressively harder much to the chagrin of you the average internet

00:02:46.480 --> 00:02:53.360
user who's just trying to bulk by toilet paper online instead of schlepping up to

00:02:50.640 --> 00:02:57.680
walmart but is there an end in sight to this arms race the way those i'm not a

00:02:55.599 --> 00:03:02.000
robot boxes work without forcing you to solve a puzzle is by tracking your

00:02:59.519 --> 00:03:06.319
in-browser behavior how fast you type how you move your mouse around even the

00:03:03.519 --> 00:03:10.239
way you switch tabs to determine that you're human and not a bot that can

00:03:08.560 --> 00:03:14.879
input paragraphs of text in a matter of seconds or move a mouse to precisely a

00:03:12.400 --> 00:03:18.560
single pixel location on the screen some engineers believe what we'll end up

00:03:16.640 --> 00:03:21.760
having is a kind of souped-up version of this it's no secret that you're

00:03:20.080 --> 00:03:25.840
constantly being tracked in some form or another while you're online so future

00:03:23.519 --> 00:03:29.920
versions of captcha may not only track the way you type remove your mouse but

00:03:27.519 --> 00:03:33.920
also keep tabs on you more thoroughly through cookies and browser activity to

00:03:32.159 --> 00:03:38.000
determine whether or not you're human such a capture would basically always be

00:03:36.000 --> 00:03:42.159
running in the background on a browser level so while it might

00:03:40.159 --> 00:03:47.200
help us beat the bots there are obvious privacy concerns in addition to the fact

00:03:44.480 --> 00:03:50.959
that bots might end up beating these tests at some point in the future as

00:03:49.280 --> 00:03:55.120
well i just hope it doesn't get to the point where all computers come with a
