Cueball appears to be asking Ponytail to write an app that determines if a given picture is of a bird in a national park. These two requirements, while seemingly about equally hard to a human, vary greatly in difficulty for a computer.
CS stands for computer science.
The title text expands on the information already given, saying that a project to develop a system that could recognize objects was intended to last for only a single summer but instead continues to this day.
the source of title text maybe is Szeliski, Computer Vision: Algorithms and Applications (2010), p. 10. --valepert (talk) 06:59, 24 September 2014 (UTC)
Google’s Artificial Brain Learns to Find Cat Videos might be useful as a description of the problem 188.8.131.52 08:34, 24 September 2014 (UTC)

Isn't there an xkcd where the estimate of 5 years of work is equivalent to "might take forever?" Rtanenbaum (talk) 13:16, 24 September 2014 (UTC)

The link in the description is to a document by Seymour Papert and the book on the project is also by Papert. Is there any contemporary evidence that it was actually Minsky who assigned the project? I think he just got interested in it later. 14:17, 24 September 2014 (UTC)

Is it possible that Randall's selection of bird rather than another naturally occurring object is a subtle reference to the Birdsnap app (http://engineering.columbia.edu/it-crow-or-raven-new-birdsnap-app-will-tell-you-0) which has solved some of the aspects of this problem? 18.104.22.168 22:02, 27 September 2014 (UTC)
Hopefully I can add that this also seems to make reference to the U.S. Forest Service intention to make everyone have a permit to take pics, etc., in national parks. https://www.yahoo.com/travel/dont-take-that-picture-the-u-s-forest-service-might-98484656432.html 22.214.171.124 (talk) (please sign your comments with ~~~~)
Post the picture to an online forum, say it's a bird, if it's not everyone will correct you as per http://xkcd.com/386/, so scrape forum and if there's a lot of attention it's not a bird, if there isn't much attention it probably is a bird. 126.96.36.199 23:06, 3 October 2014 (UTC)
A dev team at Flickr took this comic as a challenge, and set up a PoC at http://parkorbird.flickr.com/ (that seems to work fairly well). --188.8.131.52 20:08, 20 October 2014 (UTC)
- I was duly impressed. It doesn't recognize big bird very well, though. ;) Suspender guy (talk) 20:26, 17 February 2016 (UTC)
A 'picture of a bird' from a CS perspective is a reverse engineering problem. The picture is a 2 dimensional rendering of a 3-dimensional world and a 'bird' is a 3-dimensional object. It takes years for the mind of a newborn human to be able to recognize a majority of objects based on their 'first look' at a stereoscopic (two-eyes) image presented by their visual cortex. The software equivalency of this would be to create a 3 dimensional representation of objects and create a linear-algebra algorithm that can define the statistical probability that any given shape is within a certain degree of exclusion a matrix representation of the target shape (area) of the 3 dimensional object (bird) based on distance (using spacial reconstruction). It's not impossible, it's just really really hard. - nerd answer 184.108.40.206 (talk) (please sign your comments with ~~~~)
- To be honest I don't think it is impossible to replicate any function of human intelligence and mental capacity on a computer system. It just requires sufficient processing ability, appropriate hardware, and of course, an understanding of how humans do it in the first place. -Pennpenn 220.127.116.11 03:29, 17 September 2015 (UTC)
Or just give Google a little less than two years, and they'll make Google Cloud Vision API for you Gpk (talk) 20:39, 13 June 2016 (UTC)
I read somewhere that when you ask CS/IT specialist for a probable ETA for solving an interesting problem, you need to multiply the given time to the ETA by 4 and take the next larger unit (a minute becomes 4 hours, an hour becomes 4 days etc.). Can't find the source of that though. 18.104.22.168 15:47, 12 September 2016 (UTC)
GIS being "easy"
All these years later, I still struggle with the classification of "are we in a national park" as "easy"..
It 'only' requires a functioning GPS-system. A military super-project, whose initial setup cost 12 billion, still costs ~2 million a day, and whose principles of operation depend on both special and general relativity for correctness.
And that's before we add the record-keeping and (internet?)logistics involved with providing each phone an accurate GIS-database. The OpenStreetMap (most likely free/gratis source of this type of data, for a cheap app) is a massive undertaking!
(sarcasm on) GIS-lookup sure is easy! Only took a minor Manhattan-project, a literal Einstein, and an army of internet volunteers to solve!(sarcasm off)
(I'm leaving out mobile internet access while in said National Parks (Telecom operators are among the wealthiest companies in the world, and those phone-towers-disguised-like-trees don't come cheap...), because the App would probably be shipped with a hardcoded park-database, not do live queries.)

- This is about implementation of something existing, not inventing it from scratch. The use of the word "app" implies, that this comic is happening in the smartphone area, so GPS on phones should be a regular thing. --Lupo (talk) 09:57, 18 May 2020 (UTC)
- "app" sets the real-world context, but the punchline is about the comparative hardness in CS.
- For the pragmatic app-developer, "previously solved" equals "easy"; for a doctorate in computational theory, it doesn't :-)
- -- Jules @ 126.96.36.199 12:16, 18 May 2020 (UTC)
- That might be true, but this comic is definitely about developing an app, so it doesn't matter if GPS involves complicated hard- and software setups outside of the app or not. And unless you focus on the theoretical work also for a computer scientist, it is easy to use established GPS methods. --Lupo (talk) 12:45, 18 May 2020 (UTC)
now deep learning is common you not need research team and five years anymore
