You're absolutely right! Old-hat devs DO need to be more open to people not understanding things about topics noobies are actively asking questions on. Very astute! (half /s)

... That said, pointing it out does NOTHING to correct "AI" hallucinations and its rampant inability to "think". When logical bugs that aren't simply a typo are a huge quantity of valid questions newbies have (depending on language and topic), "AI" does fuck-all for learning.

K3s by itself is single-node-by-default but not single-point-of-failure-locked: you can add server nodes with k3s server --server https://<first>:6443 plus the shared token and it switches to HA etcd (needs an odd number, 3 minimum for real quorum). Two things people hit early:

• a single-node k3s uses SQLite; once you add the second server it migrates to embedded etcd automatically, but plan disk I/O accordingly
• keep an external backup of /var/lib/rancher/k3s/server/db regardless — etcd quorum loss with no snapshot is a rebuild, not a repair

If the workload is just a handful of services, plain Docker Compose with a second box and a simple DNS failover is honestly less machinery to babysit. HA k3s earns its complexity once you have operators or long-running stateful workloads that depend on reconciliations.

This is my critique on the state of AI usage and how it reflects human interactions in foss and self-hosting communities.
