Everything else has changed around us. You know, from healthcare to transportation, everything is different, but education hasn't changed.
生活中一切其他的事物都在改变。从医疗业到运输业一切都有所变化，但是教育领域仍保持原样。
It's also been a real issue in terms of access. So what you see here is not a rock concert.
在是否有机会接受教育上，这也是个切实的问题。你看到的这张图片不是什么摇滚音乐会。
And the person you see at the end of the stage is not Madonna. This is a classroom at the Obafemi Awolowo University in Nigeria.

Now, I really believe that we can transform education, both in quality and scale and access, through technology.

Everything has to change. We need to go from lectures on the blackboard to online exercises, online videos.

We have to go to interactive virtual laboratories and gamification.
