You have to constantly reup your knowledge. IT doesn't stagnate at all. Your job is to attain new certs to renew the old ones.
The A+ for instance, there is a huge difference between the content in the 802 and the more recent 902 exams. So much legacy hardware
and software was talked about in the 802 that you will only find in the jankiest of offices. Imagine test questions about parallel ports, floppies, and
zip drives
If you took the A+ in the early 2000s and don't follow technology, you wouldn't understand that all of that shyt was wholesale replaced by USB.
