Practicing violin since before birth is a thing that is just impossible to do for anyone here not to mention not many would really like to play violin. As such, it's hypothetical, abstract situation that can be discussed safely.

On the other hand, putting tremendous amount of work into preparation for Google interview is something everyone here could, but is not doing, and a good deal of people would really like to do (or, at least, they would like to work at Google). As such, it triggers defensive mechanisms, many of which we could see in the linked thread.

It's not funny at all.
