Today we-re going to talk about search engines, which are just AI systems that try to help us find what we-re looking for. Search engines can be the sort that serve up a list of results, like during a Google or Bing search, using web crawlers, an inverted index, and measuring stuff like click through and bounce back to figure out what you want to see. They can also be the kind that give you answers, like when you ask Siri or Alexa a question, relying on knowledge bases. Admittedly, these systems aren-t perfect so next week we-ll talk about bias in AI systems like this. Crash Course is produced in association with PBS Digital Studios

Oh boy, bias. here's comes the episode I've been dreading. I usually really like Crash Course but sometimes you folks go too far on the -woke-mentality.
According to the United States Bureau of Labor, about 90% of nurses are female. If this holds up globally, then showing 90% images of female nurses would not be biased - it would be an accurate reflection of reality. 85% or 95% female nurses would be biased. A more even gender distribution may be _desirable, _ but that's not the point; if I say -show me pictures of nurses, - I either want to know what a stereotypical nurse is (in which case bias is desirable, or I want to know what real nurses actually look like, in which case if I see a large collection of images I want them to have the same distribution of features (e. g. gender) as reality.
Trying to push an agenda by deliberately biasing the presentation of information, rather than doing the tough work of going out and effecting change to the underlying facts, is putting the cart before the horse. You can even do more harm than good by suggesting that the problem doesn't even exist: -Of course there's plenty of male nurses; look what happens when I search for pictures of them! -

I'm sorry but NO, search engines haven't been getting better and better at helping us find what we are looking for.
Back when google used and actually obeyed boolean search operators, it used to be an extremely powerful research tool. Now it's basically useless unless you are looking for advertisements or really basic information. For any kind of esoteric or very specific information that doesn't fit under google/scholar, google has become completely useless. It's good at showing you what it wants you to be searching for or what it thinks you are searching for, but not what you are actually searching for.

Submarine sandwiches often have a connected bread, and they're sandwiches. I also don't think hot dogs are sandwiches, but I don't quite know why. Maybe it's the way you hold it? Like, even with a connected-bread sub, you hold it so the bread is horizontal with a top and bottom, but with a hot dog, you hold it with the connection at the bottom, open at the top, and bun on the sides. Maybe that's the distinction?
Also. I wonder what percentage of CrashCourse's demographic are old enough to recognize and remember that dial-up sound? -

-Bias- is not necessarily a bad thing and oftentimes it just reflects the reality. To give another example: most elementary school teachers are female, that's a fact and it shouldn't be changed (or should I say lied to) in search engines to reflect some kind of --utopian society--.

Yeah your app doesn-t work on android. been downloading it and uninstalling it and trying again and again. doesn-t even launch.
It says -Download failed. could not connect to the internet-. I-ve downloaded the app on 4G and on WiFi. makes no difference

0: 21 - Sandwiches don't have connected buns? So Subway's submarine sandwiches are really hotdogs? -
2: 19 - Typical John Green Bot. Hank Green Bot upgraded to broadband a long time ago.

never would have thought, like 6 years ago, that CrashCourse would be producing such varied and amazing content like this
