As always, opinions in this post are solely those of my own, and not necessarily those of any organization I am currently affiliated with or have been in the past.
2026 marks 20 years since I finished my CompTIA A+ Certification and began a network engineering homelab to prepare for the Network+, so I guess that officially makes me old. I have significantly fewer cycles & less space for homelabbing now that two small kids are present in our house these days. Fortunately my lab buddy Claude Opus has been picking up the slack!
All of my recent AI use for labbing out new configs at the dayjob & homelab really got me thinking: now that you can ask an LLM to debug that running-config, error message or Ansible playbook, why even bother reading homelab blogs anymore? Who’s crazy enough to still write posts like this one without using an LLM whatsoever? Do people even want to read now that so many awesome Network Engineering Podcasters, YouTubers & even TikTockers create easier-to-digest content? Is there value in sharing your homelab’s results in public knowing that AI might “borrow” your results in a way that never steers readers to your content?
AI has made it a very different world for network engineering careers compared to when I first started blogging about my homelab in 2020. It’s a completely different universe from when I began thinking about obtaining a CCNA nearly 20 years ago, and that’s ok! Recently I got my hands on two publications which reminded me that even when it feels like AI might be throwing a gigantic curveball into my professional & personal life, it’s also opening new opportunities, some of which don’t even exist yet today. Said opportunities are so exciting that I felt a need to keep this rapidly-fading-into-obsolescence homelab blog alive to blab on this topic further 🙂
Publication #1: A Fry’s Electronics Spring 2005 Newspaper Ad
Recently my wife was going through some old storage bins and found a few old Chicago Tribune newspapers. One of which had a full 4-page ad for my favorite store as a teenager: Fry’s Electronics in Downers Grove, IL. Just one quick look immediately bought back so many memories; Windows XP Service Pack 2, “HD-Ready” televisions, AGP video cards & pre-SATA hard drives!
When I was a teen during the era of that newspaper ad, it was such easy money upgrading, repairing & reimaging home computers that got obliterated by Limewire. Nowadays anyone can reimage PCs, it almost feels like teenagers these days missed out on the glory days of computer repair 🙂 I probably spent hundreds of hours watching The Screen Savers on TechTV, reading the Mike Meyers A+ certification bible and reimaging Windows 98/XP desktops or PowerPC Macs because that was what I considered to be my best path into an IT career. There wasn’t much else out there in the mid-2000’s, and getting paid to backup/restore files wasn’t bad. I tried getting into programming since making video games felt like a dream job, but there wasn’t any great money or good wisdom on that which I could easily access at home via dial-up internet. Here in the mid-2020’s, we have amazing books for kids to learn programming basics, YouTube tutorials galore, cheap Arduino/RasperryPi gear to learn hardware fundamentals and AI chatbots to eliminate time wasters like reimaging an OS on shoddy old hardware to gain experience.
Sure, you still need to know how computers fundamentally work if you want an IT career, and I’m very glad AI & newer operating systems have made computing so much less painful than it was 20 years ago. Even if it means today’s poor GenZ teens can’t make easy computer repair money anymore. Nowadays there’s so many great Discords & Podcasts out there for these new technologists, guiding them towards way better uses of their time.
While it does feel like nearly all professional services career fields (especially IT Infrastructure and Software Engineering) face significant headwinds due to AI, I am cautiously optimistic that we’ll see less of the “Become an IT pro just for the money via our expensive for-profit training program” predatory nonsense. Calculators & spreadsheets didn’t eliminate all accountants. Computers didn’t eliminate all administrative professionals. AI isn’t going to eliminate all entry-level IT career jobs. It might significantly reduce these entry-level opportunities, but at the end of the day, someone’s gotta make the internet work, otherwise AI can’t be reached!
Since I know someone is going to ask, here’s the remaining three pages of the Fry’s ad
Publication #2: Eric Chou’s AI Networking Cookbook
A few years ago, I was putting in some firewall rules for one of the AI subject matter experts at my dayjob. He was kind enough to spend a good half hour on a screenshare showing off some fundamentals of prompt engineering for IT infrastructure work, which has really helped me when using AI to draft configs or troubleshoot. I’ll never forget troubleshooting various IPv6-only problems using whatever ChatGPT 3 & 4 models were available at SC23 Staging with that advice. About half the time, I’d get misleading answers or CLI commands that didn’t exist on the firewall/router/switch/etc with issues. This was still helpful (and ultimately led to a really good IPv6 academic paper!), but back then I certainly wasn’t going copy/paste any LLM output straight into a live production network.
Fast forward to late last year: I got an invite to checkout Eric’s book pre-release and access to some of the latest ChatGPT 5 & Claude Opus models. Without giving away all of Eric’s special sauce or my prompting style, I must say that his chapter on prompt engineering absolutely knocks it out of the park. Between that wisdom and the newer models, I’m seeing near a 100% “configuration check succeeds” rate when copy/pasting LLM-generated config output into JunOS. Perhaps just as importantly, the explanations I’m getting from Claude Opus on why my “show conf | display set | exc login | exc root” looks the way it does gives me more confidence than ever on config decisions. I still strongly feel that you need a strong understanding of network fundamentals & some Python knowledge to be an effective Network Engineer in 2026, but it sure feels like the days of memorizing cryptic CLI commands are over (unless you’re prepping for a vendor cert)! Hooray!
Now all the awesome stuff I wrote last paragraph certainly is not a free lunch; if anything it provokes the dreaded “is this going to automate away my job?” question. Fortunately I’m old enough to have lived through multiple iterations of things like “CME moving to the cloud will ruin the entire Chicagoland IT market!”, and “Openflow SDN will automate away all computer networking!” So far none of that has come to fruition, I think we’re still going to be ok for quite some time in the NetEng field, as long as you’re not getting left behind due to refusing AI’s help.
That being said, I do think there’s a lot we can learn from the downfall of the landline phone industry due to VoIP & Cell Phones taking over. If we stick to “the way we’ve always done it” like so many business phone system maintainers did when VoIP became sensible, you’re probably going to be in for a bad day eventually. Eric has written a really great section called “Network Engineer’s Advantage” where he expresses his thoughts on this topic, and I can assure you his comments are much more elegant & worthwhile than mine 🙂
Back to the homelab
Most of the posts on this blog were written before ChatGPT’s popularity exploded, and as a result have zero AI present. I haven’t used much AI at all on the recent homelab stuff I’ve done blog posts about, only the Ecobee API code and ncat syntax for doing silly Windows XP IPv6-only things were done with ChatGPT’s help. I’ve been awfully tempted to have AI update & cleanup some of my older posts (it sure would make my GCP eve-ng automation megalab way cleaner!), but I’m not going to because they are now a time capsule of what it was like homelabbing before LLM help. If someone really wants to see that content cleaned up, I guess there’s nothing stopping them from asking the LLM of their choosing to summarize my long-winded posts 🙂
Funny enough, there’s one post I wrote over 4 years ago about vimtutor’s “learn by doing” advice being applicable to those trying to learn Cisco IOS that I now feel is even more pertinent to those heavily using AI for homelabbing. I strongly believe that AI will give you some awesome shortcuts, but it will never replace understanding the network fundamentals you can only learn from labbing out a topology. It’s still worthwhile, especially if you’re just getting started. So while I might not be writing anywhere near as many homelab posts as I did pre-AI, I can assure you that sweat in the testbed network always beats blood in the prod network battle.
