I began migrating from network/hardware/IT work and into marketing after nearly 2 years of heavy lifting getting ready for Y2K. In the end, "nothing happened," so all that time and money was wasted, according to nearly every company I worked with. Even had one demand a full refund. I agreed as long as I could revert all the work that I had done. They agreed, and the next day after that their entire system collapsed.
I couldn't even get my own dad to pay for network support for his company since he would never pay my rate for anyone no matter what. After 2 other people failed to solve his problem I fixed it in 15 minutes and then he "really" didn't want to pay because it only took 15 minutes.
I was very good at what I did but got no appreciation for keeping things from breaking, only for fixing things after they broke. Marketing paid better, and I could point at real world numbers daily and justify my pay. I don't like it anywhere near as much, but at least it gets more respect than any other IT work I did.
I'm sorry your dad didn't respect your IT work...
If I move out a bit of my circle, where people do all kinds of work, I'd say that there's generally a stigma on the "IT" workers. Moreover the stigma is there even within the IT company/industry itself, where sales, marketing, non-engineering parts of management, and other similar types of supporting roles also look down on the engineering. And this unfortunately includes family members too. I learned that people are mostly envy but when you're surrounded by many it can become overwhelming - numerous times I heard phrases like "oh, you're bricklayers of a modern age" ... like wtf
I do think of all my computer work as predominantly janitorial.
On your dad:
"This is what my regular customers pay me. If I hired one of my friends or relatives I see it as my duty to pay them at least what they are worth, this is the way you raised me."
I believe this to be true btw. If someone is really your friend, you want them to do well and that means you pay what they usually get or you don't bother them and get someone else.
Idk I joined the field only like 5 years ago. Prior to knowing about programming I had a lot of respect for programmers and tech as it was this magic world to me. After having joined the field the magic is completely gone and I don't want to talk to programmers irl anymore because of how many insufferable people I've met so far. The parts where I've got credit are the simple things, fix printer, fix computer issue A,B and C or small apps like an ad free Sudoku for android which I have built for my friends. The parts I don't get credit for are the parts I get paid for. But I can see that in many industries, as soon as money is involved people are less thankful because they expect you to fulfill your part of the contract. Generally people not knowing shit about tech think that devs sit in HO all day working only 30 minutes. AI didn't help that image.
