What bad recommendations do people in your field repeat too often?

For example, I was a little surprised when I was talking to a friend who was going to go on the radio. He does work on cosmology and astronomy, and he wondered how he would explain what the applications of this work were. "Well," I said, "there aren't any." He said, "Yes, but then we won't get support for more research of this kind." I think that's kind of dishonest. If you're representing yourself as a scientist, then you should explain to the layman what you're doing—and if they don't want to support you under those circumstances, then that's their decision.

I held out for participation in the 1984 election the dictatorship called, even if I knew it would be rigged. I was warned by the lawyers of the opposition that I ran the grave risk of legitimizing the forgone results of elections that were clearly going to be fraudulent. But I was not fighting for lawyers, but for the people in whose intelligence I had implicit faith. By the exercise of democracy, even in a dictatorship, they would be prepared for democracy when it came.

There are a few things I dismiss and a few I believe in thoroughly. The former include economic forecasts, which I think don't add value, and the list of the latter starts with cycles and the need to prepare for them.

And it brings us to the debate that has been going on here: aid versus private sector, aid versus trade, etc. And someone stood up to say that one of the frustrating things is that it's been a simplistic debate. And that's not what the debate should be about. That's engaging in the wrong debate. The issue here is how do we get a partnership that involves government donors, the private sector and ordinary African people taking charge of their own lives? How do we combine all this?

Perfection is always a desired goal, but it cannot be a primary goal. Expression has to be the primary goal, because otherwise, there is no need for an actual person to be there.

In order to grasp every opportunity, you cannot — you must not — decide your "career path" in advance. Don't have a job fixed in your sights and work backwards — it can be the road to disappointment because you risk passing up opportunities that might take you "off-course."

This is what happens when we confuse morality with frugality. We've all been taught that the bake sale with five percent overhead is morally superior to the professional fundraising enterprise with 40 percent overhead, but we're missing the most important piece of information, which is: What is the actual size of these pies? Who cares if the bake sale only has five percent overhead if it's tiny?

AI without validation is too unreliable to be of use in any serious application.
