+  "This is the \"Are you tired of *this*?\" part of the infomercial.  Read the next few paragraphs
+and picture me, in black and white, struggling to hold a large stack of boxes, all labeled
+\"software.\" I continue struggling to balance the boxes as you read.  When you've reached the last
+paragraph of the section, I fall over, the boxes land on top of me and all over the floor, I'm
+covered in spaghetti, and in an exasperated voice I shout \"There's gotta be a better way!\"
+
+When setting up a new computer for software development, I want to go from `git clone` to `make` in
+as little time as possible (adjust that for your VCS and build system of choice.)  In the old days,
+this meant manually installing the dependencies through the distro package manager.  If things are
+organized, the project README will have a list of what is needed and it's not so bad.  If things are
+less organized, it's a cycle of installing packages and running `./configure` or whatever until it
+succeeds.  Hopefully none of the dependencies are too new to be found in the distro.  And when
+working on multiple projects, hopefully there's no conflicts between the dependencies required for
+each of them, because your development environment is the entire system and there's no way to
+isolate different projects from each other.
+
+Of course, different programming languages provide their own sets of tools for managing multiple
+projects.  Python has virtualenv, Ruby has rvm and bundler, Node has nvm and npm, etc.  But their
+domain is restricted to only the dependencies for that language and their runtimes.  A system
+package manager is needed to bootstrap their use.
+
+Nowadays it's \"just use Docker.\" Docker's take is that all this package management stuff is just
+too complicated.  Instead, just create a disk image per project that encapsulates this hodgepodge of
+package managers and bespoke, artisinal, small-batch builds that gets run in isolation via Linux
+namespace magic.  It works, of course, but I think Dockerfiles are clunky and the rather extreme
+level of isolation is usually unnecessary and makes things overly complicated for projects that need
+to interact with, say, the windowing system of the host computer.  A lot of people are happy with
+Docker, though.  Maybe you are, too.  That's fine!
+
+What I really want to say is \"Computer, provision a development environment containing Guile 3,
+SDL2, make, and texinfo!\" and have Majel Barrett-Roddenberry tell me that all of those things have
+been made available to me on my host system.  No container, no virtual machine.  It shouldn't matter
+if I have Guile 2 installed system-wide, Guile 3 should still be what's used in the context of the
+project.  This is how Guix works and it's very good and cool and I'm going to tell you all about how
+I use it."
