I feel like the people I interact with irl don’t even know how to boot from a USB. People here probably know how to do some form of coding or at least navigate a directory through the command line. Stg I would bet money on the average person not even being able to create a Lemmy account without assistance.
You’re fortunate that your field happens to be reasonably accessible to common people. For example, if you’re a production engineer in a company that manufactures network infrastructure, it suddenly gets very hard to even explain what you do for a living. Normal people may have seen a router, but they’ve never even heard of switches. Regardless, they never paid much attention to network hardware, because they didn’t have to.
Climate is a lot harder to ignore. Everyone has thought about these things at some level. Everyone has heard about climate change at school, on TV, news articles etc. People also experience these things on a very personal level. Only very few people can say the same about network switches, let alone submarine line terminal equipment.
There are even more obscure fields out there. The relatives of those professionals just know that their nephew does something technical and hard to understand. I guess those dinner table conversations might gravitate towards some easier topics.
I’ve played with switches before, and some DIY electronics, and have done some network admin. I’ll grant that the actual internal electronics and software are far to complex for even me to understand.
But again, if you talk to someone with some interest in what you’re doing, you can find a level they they can understand. Maybe using metaphors like human-operated old-school telephone switch boards, that’s an image that most people will have seen, and can understand at a coarse conceptual level. You CAN have an interesting conversation at the level, if YOU want to be interested in it (and if they do, which is partially contingent on you being able to connect with them in the first place).
If you think climate is simpler or more accessible, I’d suggest you have a quick go at explaining the Navier-Stokes equations, Darcy’s law for fluid flow through porous media, or why convective storm activity needs to be parameterised in climate models (and at what scale it doesn’t). Climate isn’t easier, or more accessible than network admin - both require years or tertiary education to start understanding even parts of the underlying principles, and no one person understands either field completely. It IS probably more familiar for most people, because it’s in the media all the time. But again, that’s just a matter of finding the extent of their knowledge and interest, and coming up to their level.
