We should spend the next decade focusing on the technologies, [governmental] policies and market structures that will put us on the path to eliminating greenhouse gases by 2050. It's hard to think of a better response to a miserable [year of COVID-19 disruptions during] 2020 than spending the next ten years dedicating ourselves to this ambitious goal.

Just giving people devices has a really horrible track record. You really have to change the curriculum and the teacher. And it's never going to work on a device where you don't have a keyboard-type input. Students aren't there just to read things. They're actually supposed to be able to write and communicate. And so it's going to be more in the PC realm—it's going to be a low-cost PC that lets them be highly interactive.

I laid out memory so the bottom 640 K was general purpose RAM and the upper 384 I reserved for video and ROM, and things like that. That is why they talk about the 640 K limit. It is actually a limit, not of the software, in any way, shape, or form, it is the limit of the microprocessor. That thing generates addresses, 20-bits addresses, that only can address a megabyte of memory. And, therefore, all the applications are tied to that limit. It was ten times what we had before. But to my surprise, we ran out of that address base for applications within—oh five or six years people were complaining.

I [have become] convinced of three things: 1. To avoid a climate disaster, we have to get to get to zero {net emissions by the year 2050}. 2. We need to deploy the tools we already have, like solar and wind, faster and smarter. 3. And we need to create and roll out breakthrough technologies that can take us the rest of the way.

The success of the Nigeria programme hinges on the active participation of everyone to make sure that all children are reached by National Immunization Days (NIDs), Immunization Plus Days (IPDs) and the routine immunization programme, if the country capitalizes on the commitments I've heard in the past two days, Nigeria can lead the way to a polio-free Africa.
