CLI is great from *NIX perspective and I believe most of us had used it extensively in the past. I still use CLI but if and only if it suits as the best tool for the problem I'm working on. The fact is, that the paradigm has changed, therefore the way we interact with our computing devices.

IMHO, bigotry is not only bad in politics. We have to embrace the change, learn new tools, improve, share our knowledge and not only make our jobs better for ourselves, but also for others. Especially for rookies, who will have to be doing more tomorrow than what we do today. I don't believe `libcaca` has anything to serve this purpose.

Using mutt instead of gmail; I'd ask "Why?". We don't need to stick with the tools we've used 10 years ago. If I'd be looking for a challenge as a sysadmin, I'd learn ways to better utilize cloud environments, look for better ways to serve static content for large volume systems, improve my tool base for managing geographically distributed servers, learn about the requirements of the new era of real time web, how to deploy node.js on my servers, etc.
