lastly, CLI dead ?
In the spirit of rampant contrariness, given even M$ have begun to use command lines and config files more in their server OS I suggest that the CLI may even make a come back. Very secure, quiet, mostly private, powerful if user RTFM and very low on resources. Given the amount of junk code running on idiot smart phones, phabulous phailing phablets and other end user devices I forecast <drum roll> a return to end user devices that make phone calls and resemble smaller versions of IBMs smart terminals.
