I love stuff like this. I've always wanted to find a community that collaborates to determine as much as possible the rough range of the total cost, either in man hours, dollar amount or other metrics, of things we see, know, and interact with every day. I think it is even more interesting if you try to estimate the cost of the research the thing depends on (which greatly scales up the complexity but also the fun of the exercise). For instance, what is the manhour cost of google.com historically? You can approach it in so many different ways - revenue analysis, # of employees in google search team over the years, or just guess at how much you would need to build google.com yourself today. Subreddit suggestions for different styles of this kind of activity: === /r/resetPrice Imagine that the infrastructure of the world has reset to the stone ages but we still retain all modern knowledge. What's the price, in man hours, of rebuilding things that we use every day and take for granted? What is the reset price of google.com? What is the reset price of Seattle? What is the reset price of a mechanical pencil? === /r/CTMH Cost in Total Man Hours What's the CTMH of the NY philharmonic orchestra playing for one evening? What's the CTMH of developing the entire iPhone phone line series, from original to current model? Also similar - /r/ETEB - Estimated total effort to build
