Fukushima Disaster 3rd Year Anniversary: My Story

I was there, a witness of the near apocalypse, one of the biggest earthquakes in the history of Japan that brought the worst tsunami Japan has ever recorded and the worst nuclear meltdown the world has ever faced.


March 11, 2014 marks the 3rd year anniversary of the Great Tohoku Earthquake and the Fukushima nuclear disaster in the TEPCO power plants. I still remember this day very clearly since I was back then working at the Apple Store in Shibuya and was about to start my shift. The shock wave hit when I was on the Apple Store basement getting ready to work around 3pm in the afternoon. The sensation was unlike any other earthquake I had experienced in Japan, this one felt different from the beginning a deep shake you could feel down to your bones. I knew at that moment this one was going to be the Big One the one you are always waiting for, the one people always said was going to hit in the next decade. I ran upstairs and saw all types of reactions, customers running outside the store confused and panicked others still inside the store like nothing had happened. Me, I just wanted to witness it all, be a first row spectator of this massive event, a witness of apocalypse hoping to live to tell the story, and so I did. Back then all I had was a cheap HTC cellphone with a terrible camera. All I did was take a 1 minute clip of what happened outside the store. I wish I had the phone I have today!

Criticality 3rd Year Anniversary

This is a short clip I uploaded minutes after the earthquake and probably the first clip uploaded of the event. Immediately after it happened I ran to one of our Macbooks at the store and uploaded the video to Youtube, 20 thousand views on the first day.  That same week I began this blog a journal of the tragedy and a place to talk about the disaster to the world.  Since then I have been posting regularly about Fukushima, the dangers of nuclear energy and general awareness topics.  Criticality is a space where curiosity, common sense and human preservation reside.


Cosmos by Neil Degrasse Tyson

Sunday March 9th will be the premier of the remake of Cosmos with American physicist Neil Degrasse Tyson.  The original series conducted by Carl Sagan in 1980 was a series of 13, 1 hour episodes that narrated a visual journey through space and the universe.  Although the 1980’s Cosmos series lacked the realistic special effects we have nowadays it had one of the greatest genius of all time, Carl Sagan.  Sagan’s unique tone of voice, his communication ability and passion towards knowledge and discovery made Cosmos a really inspirational TV show, that changed the lives of many.  Neil Degrasse Tyson has a huge challenge today to carry on with Sagan’s legacy and timeless show, we hope he will not disappoint the audiences.  Tyson carries on with the Cosmos legacy with more than 30 years of advancements in special effects and computer graphics animation and new discoveries in quantum physics, space exploration and discoveries in astronomy.

Here is the official Cosmos: A Spacetime Odyssey.


The Problem with Facebook and the Monetisation of Socialisation

Facebook is keeping things from you.  Every day you increase the pages and friends you like this means the amount of posts that appear in you timeline will gradually increase overtime.  Because you will be unable to see all the content unless you are all day, Facebook has developed advanced filtering systems to distribute posts in your Newsfeed that are “relevant” to you.  This is  done through a complex algorithm called EdgeRank which uses thousands of variables to rank Facebook friends and Pages on your Newsfeed.  The problem with this is that one strong factor that influences the EdgeRank is your level of agreement towards your friend or Page you liked, this is measured mainly by your interaction with Likes, clicks, comments and share.  Since normally you do not Like, click or share content you disagree with Facebook assumes this is content you do not want to see in your Newsfeed, therefore it will become an echo chamber of self affirming views, with things you already think and believe.  But this is just part of the problem, because the remaining posts and content hidden from you must now pay to reach you. S4FDDS857CPS

Post reach and EdgeRank

Haven’t you asked yourself, why x-friend or y-Page is not appearing anymore in your timeline?  Well the main reason is because the EdgeRank algorithm has decided to bury their content from your timeline in order to give space to content you are more likely to engage with.  The reason is because the post will reach only users who are more likely to engage with it, which is usually less than 30% of you fan base.  With EdgeRank Facebook has automatically reduced the organic reach of every Page by using strong filters that distribute content based on fan potential engagement.  The problem with this is that unless you pay through Facebook Ads or Post Boost you wont be able to reach the remaining 70% of your fan base at all.

EdgeRank and the Monetized Socialization Business Model

The EdgeRank algorithm allowed the establishment of a competitive model within Facebook, where Friends and Fan Pages struggle to create frequent and engaging content to avoid being buried into oblivion.  This is the foundation of Facebook’s business model which works by monetising the socialisation of Pages and Users through Post Boosts and Facebook Ads.  Unlike Twitter and Youtube, where users and content creators distribute their content for free and equally throughout the social network Facebook has restricted the social reach of user content by creating a business model that forces them to pay to increase their reach.

In Youtube for example the incentives of users, content creators and advertisers are aligned.  Content creators get paid for content by the advertisers who want to reach the most amount of users and users get their digital oxytocin* hit by watching fun videos, its a win-win situation.  While on Facebook Fan Page owners have no way to monetise their content and the only one who make money from the platform is Mark Zuckerberg.  Advertisers make money indirectly, but content creators’ only reward is having “engaging” content, a bunch of likes, comments and shares.

Pros and Cons Facebook’s EdgeRank


  • New users have a legitimate shortcut to increase engagement and fan base rapidly
  • Page owners who have abandoned their Pages for long periods of time can reactivate their reach by boosting posts
  • The EdgeRank algorithm can actually filter a lot of irrelevant content that could potentially flood your Newsfeed
  • Reduced CPM price by actually providing engaging Pages a cheaper cost per reach.


  • Unfair competitive model. Page owners with advertising budget will always have the edge over Pages that don’t pay
  • The EdgeRank algorithm isn’t perfect and could vanish content from your NewsFeed that could actually be interesting to you
  • Facebook Ads and Post Boosts have become a great shortcut for advertisers on Facebook who are invading users’ NewsFeed with commercial content without having their consent
  • Facebook ultimately decides what you should see or not

Do you want Facebook to decide what you see?

The question is, do you really want Facebook to decide what you see or not?  This is basically EdgeRank’s task is to learn about what you like and love and distribute it in your timeline.  This can actually convert your NewsFeed into an echo chamber of self assuring views and thoughts by only showing you things that you agree with.  EdgeRank’s t. But do you only want to see all the time things that you potentially like and love? This is actually a moral issue since Facebook is assuming the role of judge of your taste and opinions. Hmmm??

This is an interesting video by Veritassium which explains the problem with Facebook really well

*About Digital Oxytocin. What is your incentive when using Facebook? Some study out there by CalTech California Institute of Technology discovered that using Social Media stimulates the release of oxytocin, a special molecule that makes us feel trusted.  Social Media is basically an unlimited source of oxytocin, where you can find readily available trust 24/7, and you keep come back every time for more.  Scientifically this is a way to demonstrate a strong biological incentive that drives people into using Social Media, and specially Facebook which is the most widely used social network which the study concluded is the Social Network that stimulates more oxytocin release.
