On November 14, 2018, Zack commented on Challenge.Gov – A Model for Government Crowdsourcing :

I think crowdsourcing of ideas by programs like is a great concept, but I think the greater challenge lies with finding the technical talent to effectively execute on the ideas. I think state and local governments should partner with tech companies rather than individuals to execute on the best ideas that they have generated, similar to what was done in Mexico. The result could be a win-win, with the tech companies receiving positive publicity for helping the public sector and the government receiving the technical support needed to carry out its initiatives.

On November 14, 2018, Zack commented on Crowdsourcing as the Future of Secret Cinema :

Really interesting article! Secret Cinema seems like it has developed a really engaging experience for its fans through its use of crowd sourcing. I think your idea for the script contest is really interesting, although I do have some reservations with that concept. It seems like Secret Cinema has strategically targeted “colt-classic” films like Star Wars and Moulin Rouge for its events. If they open up their repertoire to new concepts and scripts, will they be able to garner as much excitement for their events? Or should they limit these scripts to rewrites of classic films?

On November 14, 2018, Zack commented on YouTube | Machines Cleaning Up Human Content :

Fascinating article! I think the most interesting part of this challenge is deciding where to draw the line with what is considered inappropriate for YouTube. Will there be a point at which the machine learning algorithm will become so advanced that it is considered the best and most unbiased judge for public content? Also how will the machine learning algorithms change over time as cultural and social norms shift? I think these issues are especially challenging for a global product like YouTube that serves people from a wide range of geographies and cultures.

On November 14, 2018, Zack commented on Amazon Go: The Future of Retail? :

Such an interesting idea! My concern with the “Amazon go” store concept would be privacy. As large tech companies gather more and more information about their users, the public has started to push back against these companies mining their data. Understanding your purchase history is one thing, but using facial recognition and other technologies to recognize you when you enter a store could cause more controversy for Amazon. How will Amazon ensure that shoppers’ data is secure and not used in the wrong ways?

On November 14, 2018, Zack commented on Adding Value In Nike’s Production Line :

Really cool article. This type of application for additive manufacturing makes me think of how manufacturing can become increasingly decentralized in decades to come. Looking at your cost estimates for packaging, shipping, and retailer margin, I can see a future where individual households can have their own manufacturing capabilities in the form of highly-advanced 3D printers. In this model, individuals could purchase shoes as digital CAD files from companies like Nike and simply print their shoes at home, completely circumventing the traditional supply chain and saving costs as a result.

I really enjoyed your essay. I think the most intriguing application that you mentioned is re-manufacturing. I have read that auto part suppliers are often required to maintain capacity for producing parts for years after the model has stopped being produced or else hold significant inventory for spare parts. I think AM could provide an alternate approach to the spare parts business, where parts could be printed in a JIT manner rather than holding onto inventory for years to come, thus providing significant savings to the auto parts suppliers.
