Im absolutely with you and want to upvote that part of the comment x100. Unfortunately it's often considered a fairly spicy opinions.
Entire frameworks (Rails) are built around the idea of typing as little as possible. Others can't even be mentioned without the topic of boilerplate/keystroke count causing a flame war (Redux).
A lot of engineers equate their value with the amount of lines they can pump out, so there's definitely a demand for tools like these.
There's also some legitimate stuff. There's a lot of very silly thing I have to google every time I do because I have a bad memory. It saves the step of googling. In a way, it was the same debate around autocomplete at the very beginning, but pushed to the next level. Autocomplete turned out to be a very good thing (even though new languages and tools keep coming out without it).
