I would hazard a guess that we have found fossilized human remains of at least a thousand different specimens in South and East Africa, more or less complete at that. I think this is where the prelude to human history was primarily played out. ↗
We are concerned that, in a few years time, this place of discovery, with its wealth of human fossils, the like of which can be found nowhere else in the world, could be completely destroyed. ↗
If you want to solve very complex problems, you will have to end up letting machines work out a lot of the details for themselves, and in ways that we don't understand what they are doing. ↗
I'm not good at future planning. I don't plan at all. I don't know what I'm doing tomorrow. I don't have a day planner and I don't have a diary. I completely live in the now, not in the past, not in the future. ↗
