Another interesting aspect of PokemonGo is the new forms of monetization that the app has. For example, retailers or restaurants can pay Niantic to “send” Pokemons to their locations in order to attract potential customers.

I am also an enthusiast of self-driving cars. Beyond the benefits that you mentioned, I am excited about the potential reduction in traffic congestion because autonomous cars can travel at higher speeds with less space in between them.

I find this debate about technology advances and job destruction very important. I understand that the impact on people whose jobs are disrupted is enormous, but overall I see technology advances as net positive for society, so far new tech has created more jobs than destroyed.
My opinion is that rather than attack new technologies, we should focus on creating conditions for people whose jobs are disrupted to develop new skills that enable them to find new jobs created by tech.

On November 20, 2016, abcd commented on Macy’s: A Beacon of Technology :

Interesting idea, there seems to be a trend of tracking consumers in many department store. According to a NY Times article, stores like Nordstrom are using wi-fi and cameras to track user behavior. I prefer the Beacon technology to these other forms of tracking because it is more explicit to users, wi-fi tracked customers may not realize they are being tracked.

On November 20, 2016, abcd commented on No More Dashing Out To The Store :

Very interesting post, I also find the dash button concept very clever. But I remember reading a WSJ article that mentions that users are not using the dash buttons. Among the causes for this issue is the fact that the buttons do not display product prices. Is it possible for Amazon to include a price display in the buttons?

On November 7, 2016, Mariana Aversa commented on Coca-Cola – Refreshing the World? :

It is very interesting to understand how Coca-Cola is working towards achieving sustainability, especially how it managed to reduce by half the amount of water in every liter of Coke. Would be interesting to understand the cost impacts of such measures. Is Coke spending a lot of money to become more sustainable or do these measures actually reduce the company’s costs?

Interesting post. I see some parallels to what is happening in Brazil and to Rahil’s post about tea production in India [1]. In Ghana, Brazil and India, extra irrigation has been a widely adopted solution to fight decreasing rainfall. But I wonder whether the costs associated with this solution are sustainable in the long term. Some companies in Brazil and India are trying to develop new varieties of plants which are less vulnerable to droughts and can grow without irrigation. Do you think this can also be applied in Ghana?


On November 6, 2016, Mariana Aversa commented on Mayday: Mother Earth Code 7700 :

Very interesting! This post reminds me of some initiatives that Boeing together with some Brazilian airlines and Embraer (also an airplane manufacturer) are implementing to reduce greenhouse-gas emissions. First, Brazilian airline GOL began the first commercial route with farnesane, a recently approved renewable jet fuel. GOL has committed to fly its Boeing 737 fleet with a 10 percent blend of the renewable fuel on its U.S. to Brazil routes [1]. Farnesane meets the rigorous performance requirements set by the aviation industry and can reduce greenhouse-gas emissions by up to 80% compared to traditional petroleum fuels. Second, Boeing and Embraer opened a joint sustainable aviation biofuel research center in Brazil [2], where the sugarcane ethanol accounts for almost 50% of the total fuel usage in the automobile industry but still less than 1% in the aviation fuel usage.


I agree that more needs to be done because all the current solutions are strictly temporary but cannot see how such a small nation can structurally tackle this climate issue without cooperation of the large countries. Sea levels will continue to rise and overcome walls and re-erode beaches. Moreover, as temperature goes up, the negative effects happen faster so the returns on the temporary solutions might diminish over time.

On November 6, 2016, Mariana Aversa commented on How is H&M delivering sustainable fast fashion? :

H&M sustainability challenge reminds me of our class discussion about IKEA. I appreciate the fact that the company is making considerable changes to its processes and products to reduce its carbon footprint but since its fast fashion business model is unlikely to change, I find hard to call H&M sustainable. Eventually, if its recycling efforts gain traction, the company will be able to offset the negative environmental consequences of the fast fashion model.
