I heard a speech by a former president of Sony.

I went to a local bookstore and happened to see a lecture by Kazuo Hirai, former president of Sony. I listened to it.

The technologies that have largely bought me my life are Windows 95 and PlayStation.

Without Windows 95 we would not have been able to make games. Without PlayStation 2, Melty Blood might not have made it overseas.

I am sure that Mr. Hirai, who gave this lecture, was one of the people who changed my life.
