Kay: Go to a blog, go to any Wiki, and find one that's WYSIWYG like Microsoft Word is. Word was done in 1984. HyperCard was 1989. Find me Web pages that are even as good as HyperCard. The Web was done after that, but it was done by people who had no imagination. They were just trying to satisfy an immediate need…
Binstock: You seem fastidious about always giving people credit for their work. Kay: Well, I'm an old-fashioned guy. And I also happen to believe in history. The lack of interest, the disdain for history is what makes computing not-quite-a-field. Binstock: You once referred to computing as pop culture. Kay: It is…
At the highest level, the major hardware components of most boards can be classifi ed into fi ve major categories: Central processing unit (CPU). The master processor. Memory. Where the system’s software is stored. Input device(s). Input slave processors and relative electrical components. Output device(s). Output…
If we somehow manage to make an atomic size computer, it would mean that the dimension, the linear dimension, is a thousand to ten thousand times smaller than those very tiny chips that we have now. It means that the volume of the computer is 100 billionth or 10^-11 of the present volume, because the volume of the…
The great discovery of Bennett and, independently, of Fredkin is that it is possible to do computation with a different kind of fundamental gate unit, namely, a reversible gate unit. I have illustrated their idea--with a unit which I could call a reversible NAND gate. It has thre inputs and thre outputs. Of the…
The first thing that you would worry about when things get very small is Brownian motion--everything is shaking about and nothing stays in place. How can you control the circuits then? Furthermore, if a circuit does work, doesn't it now have a chance of accidentally jumping back? If we use two volts for the energy of…
I have estimaged how many letters there are in a the Enclyclopaedia, and I have assumed that each of my 24 million books is as big as an Encyclopaedia volume, and have calculated, then, how many bits of information there are (10^15). For each bit I allow 100 atoms. And it turns out that all of the information that man…
