I had a similar thought recently. People who are currently in their 20s and 30s had a unique privilege of growing up when fully-featured computers appeared in almost every household. A bored 13 year old kid getting a Pentium-166 desktop for Christmas is much more likely to start tinkering with the system, learn to program, hack, etc. than if his or her first computer was a walled garden iPad. Now with the huge success of smartphones and tablets, it may well happen that most households of 2025 won't even have a computer suitable for anything but media consumption and "apps".
