Because it would be nigh impossible to learn every tech/language for every job you are considering interviewing for. Would you spend a week learning a new tech

  You don't need to learn every tech/language that the interviewers want, you need to learn a language that the interviewers want. If you have learned 5 languages in the last 5 years, at least one or two (unless you've been really weird in selecting them) would be fresh and popular, and there would be a bunch of different employers that are recruiting for one of those 5 languages. The big problem is putting all your eggs in one basket, which is bad if that one technology goes out of demand (as the grandparent painfully experienced). It's not something you do for hiring in a week before interview, it's something you do all the time in the years before as a part of your natural interest and "sharpening the saw" - if you spend the last 5 years working with technology A, a person who is "capable of picking up new technologies and languages with ease" would have picked up technologies B, C, D and E during that time anyway, and can go out to employers who want B truthfully claiming that they learned B back in 2015.
