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.

It helps to set ambitious goals and commit to meeting them, the way countries around the world did with the 2015 Paris Agreement. It’s easy to mock international agreements, but they’re part of how progress happens: If you like having an ozone layer, you can thank an international agreement called the Montreal Protocol.
