Of course, my decision faced plenty of criticism. One of my fellow Japanese CEOs went so far as to call the plan “stupid” – notable, in a country where executives do not generally criticize one another in the press. Clearly, I would have to fight an uphill battle for cultural acceptance. But I was not deterred. A seismic shift demands that we adapt to a new landscape, and a seismic economic shift is exactly what Japan has undergone in recent decades, driven by the forces of globalization and digitization. The only way to compete in this interconnected internet age is to speak the language of the market – and that language is English.

I continued the work on dorsal, discovered the recessive phenotype and interpreted the phenotype postulating a gradient determining the dorsoventral axis. At that time, gradients were not widely accepted as mechanisms, in particular biochemists were highly sceptical, however the Tübingen influence made such models attractive to me.

What I want to do this morning is share with you a couple of stories and talk about a different Africa. Already this morning there were some allusions to the Africa that you hear about all the time: the Africa of HIV/AIDS, the Africa of malaria, the Africa of poverty, the Africa of conflict, and the Africa of disasters. While it is true that those things are going on, there's an Africa that you don't hear about very much. And sometimes I'm puzzled, and I ask myself why. This is the Africa that is changing, that Chris alluded to. This is the Africa of opportunity. This is the Africa where people want to take charge of their own futures and their own destinies.

Under the stress of the event, we felt, the soldiers' true nature would reveal itself, and we would be able to tell who would be a good leader and who would not. But the trouble was that, in fact, we could not tell. Every month or so we had a "statistics day," during which we would get feedback from the officer-training school, indicating the accuracy of our ratings of candidates' potential. The story was always the same: our ability to predict performance at the school was negligible. But the next day, there would be another batch of candidates to be taken to the obstacle field, where we would face them with the wall and see their true natures revealed. I was so impressed by the complete lack of connection between the statistical information and the compelling experience of insight that I coined a term for it: "the illusion of validity."
