Thinking about technology

So yesterday I started reading through my old notes from when I was studying for the CCNA exam earlier this year. I was worried that I was getting rusty, and boy was I right. It's a bit upsetting to see how much I've forgotten since April when I passed the exam. I want to be able to administer all the equipment I have, which is a daunting task, so I need to stay fluent in the Cisco IOS platform. Eventually I want to start using Ansible with my Cisco gear to make it easier to administer. With Ansible, I wouldn't have to log into each device individually to check on things or make changes, so based on what little bit I know about Ansible it seems worth the effort. But I'll still need to have a basic understanding of Cisco IOS to make it work. Here's a list of things I've had to learn to use to host this website: - HTML and CSS - Python and Django - Git and GitHub - Linux - Apache - Proxmox - Mikrotik RouterOS - Networking - setting up my own AS - getting a business license ...and that's just for this one website. It also doesn't count the number of years I've spent messing around with computers, learning how hardware works, installing operating systems, using Windows (ugh) and I'm sure I'm forgetting at least one or two other things I had to pick up along the way. It's mind-boggling to think of all the various technologies required just to make the Internet and Web work properly, and I've probably just scratched the surface (hopefully it's a deep scratch). I struggle to think of what comes next. It seems like every few years a new technology comes around that will supposedly change everything. I wonder what I'll have to master next.
