Are you joking? I know that streamlined software has made it unnecessary to develop a lot of skills that used to be common among PC users, but Zoomers being unable to unzip files is too big of a jump for me to take your statement at face value.
This article is written in French (so you might have to translate the page) but it sums up pretty well what kind of challenges zoomers face when working with computers:
You must be registered to see the links
TL;DT;DR (Too Long; Didn't Translate; Didn't Read):
Most Zoomers don't know how to send an email, how to attach a file, how to copy and paste, how to open a Word file, and how to copy or use a link.
From other sources, you can learn they don't know the difference between a file and a folder, they don't understand the concept of a hierarchy, and they think they are facing a bug when they are warned they can't save a file in a folder because a file with the same extension already uses that filename (while being in computer-centric college curriculum).
Some people even explained how Boomers are more keen on learning how to use a computer than Zoomers are. When confronted, they often replay with things along the lines of: "I don't see any use for it. The future is on mobiles, not on computers" ignoring entirely the fact that mobile software is developed on computers. The most important thing to take from all of this is that it's not only that they do not know "how to", but it's also that they don't even want to know anymore.
This whole situation is why some computer science, engineering, or programming curriculum now start with complete courses or modules about just the computer basics: how to turn it on, how to go on the internet, and how to communicate with others (while not using TikTok or Snapchat to do so). Literally tens (or hundreds) of hours poured into basic stuff before learning anything related to the chosen matter.
What could possibly go wrong in the next 10-20 years? This is fine...
