\maketitle
Where are we? How did we get here? What’s the future? I’ll try to
answer these questions, by looking outward in both space and
time. Here are some ideas.
Don Knuth started \TeX{} in 1977. The present version is a direct
descendant of the 1982 version. Only at the end of the 1980s did hard
disc drives cost less than \$10 a megabyte. Today, for about \$100 I can
buy a pocket computer that connects to a ubiquitous network. It has
gigabytes of solid state storage. It fits in my pocket, more easily
than a book.
Today software that implements Don Knuth’s wonderful mathematical
typesetting algorithm and fonts can be downloaded for free. And this
software installs itself, and is interactive. In real time it previews
\LaTeX{}-encoded mathematics, as I type it.
My monitor is 40 inch, 3840$\times$2160 with 24 bit color. It’s no more
expensive than a \acro{TV}. (In fact, it is a \acro{TV}.) It cost
about \$450. It’s not my virtual desktop. It’s my vertical desktop,
about the same size as my horizontal desktop.
As often as not, when I read beautifully typeset mathematics, it’s on
my vertical desktop, as part of a web page. The only time I really
need a PDF is to send a file to be printed. So that I can put it on my
horizontal desktop, and write on it with a pen.
And the interactive mathematical typesetting software. It’s built on
\acro{HTML5}, and it’s called MathJax. And the future of \TeX{} and
\LaTeX{} and our community. To succeed, we have to change, and also
keep things the same. Linus Torvalds did something much the same with
Unix, to create Linux.
By the way, my wonderful pocket computer that typesets
mathematics. It’s also known as a mobile phone, and it runs the Linux
kernel.
