;;; google-stuff.el --- Working with Google infrastructure from Emacs -*- lexical-binding: t -*-
;; Author: William Carroll <wpcarro@gmail.com>
;;; Commentary:
;; First, I must opine. Feel free to skip this section. In general, it seems
;; that the typical programmer's workflow suffer from what economists call
;; "inelastic demand". This means that any increase in the price of something
;; plummets the demand. Another way of saying this is that programmers are
;; "price sensitive" when it comes to adopting new workflows.
;;
;; For us, any deviation from our "established" workflow feels costly. This
;; makes sense to me because programming is already mentally taxing, so any
;; additional taxation can sometimes feel unbearable. Until programming changes
;; dramatically and we relieve our dependence on files and text for modeling
;; complex applications, this price sensitivity will most likely remain the
;; status quo. Therefore, it's critical to reduce the price of experimenting
;; with new tools such that new, superior workflows may emerge. In this vain,
;; this module attempts to surface "luxury tools" (i.e. dependency pruners, code
;; linters, code formatters) via Emacs to reduce the price of experimenting with
;; them.
