I, for one (and i think most coders and tech people will agree with me), enjoy the snarky personality of software such as WordPress and chrome. Most of it is nerd culture or pop culture references.
"He's Dead, Jim!" is a Star Trek Reference (Dr. McCoy speaking to Captain Kirk, informing him that someone died). It's pretty obvious that the tab crashed, why do we need to have super dry, emotionless (in keeping with the trend "Vulcan") language?
When something goes wrong, i'd rather have the snarky cultural references to lighten the mood.

I have always appreciated this type of personality in software (as most under 40 probably do).
The software is starting to be toned to the people that will be using it the most moving forward i.e. the tail end of genX and the melennials, etc. And i personally think it should stay that way
