What should I invest time learning these days? I'm a sysadmin and want to keep growing and not become stagnant. What would you all say are some worthwhile technologies/topics to invest time into learning? Ideally, I'm hoping to learn something that's both useful in the IT job market (future-minded) *and* is also fun/interesting to me. That'd be great to check both boxes if possible. A short list I came up with so far that sound interesting to me (unsure how many of these are useful in the future IT job market): * Docker/containers -- I have experience with VMs but next to none with containers * OpenClaw -- maybe set it up in a container and play with it (carefully) * TryHackMe/HackTheBox learning path -- I have some cyber sec experience but could also learn more/get hands on and refresh my knowledge * Cryptocurrency -- I have zero hands-on knowledge. Seems like it'd be a good thing to know more about, ie: how do you pay someone in crypto, etc...…
