No long term 3 day work week for HVAC guys or electricians.
Luckily there's not much AI can currently do in my position other than market bids. It can likely calculate water demands & power flows FAR faster than us humans but with the amount of bad data sets out in the system, humans are currently running circles around AI. Market bids though, either in real time 5- & 15-minute markets or in the day ahead market, AI has been implemented with pretty solid success rates. Where I'm at it's still a human doing the bids but I do know of a couple entities that use AI for that function successfully.
I'm in a meeting right now with people in France. Saved me from flying there. I can see slides and participate in real time. Seems so common today but we didn't have this technology when I started working.
I'm also in utilities. We have a saying that the closer you are to the equipment, the more secure your position is. I moved out of the power plants & into grid ops a decade ago but could/would fall back to plant operations if needed.
No one, the tech will be deflationary just like every other tech.
Well simple, Al would. Allen would be brought thought the court system and the money Al made would be distributive to the victims and deceased loved ones. After a nuclear catastrophic design accident, Al would not be trusted again till time would show Al could redeem himself. If I was Allen, I would watch myself and not get into that field of design. I would go into bridge engineering, nothing can go wrong there.
"They" tried that with me.... I had a phone that was paid for by the company but I was free to use as my personal phone (if I was told it's strictly for work, I would have turned it down anyway). Once that was given, and I didn't answer a couple calls after hours from the owner, he said (I'm paraphrasing but not exaggerating) "you're expected to answer your work phone anytime someone calls". I was mowing at the time of the call and I either didn't have my phone on me or didn't hear/feel it ringing. I was that when I did call back....outside of work hours. It happened a 2nd time and a voicemail was left with the same general message, which I ignored. The next day, I told him not to ever leave a message to me like that or try to speak to me like I'm his child. Yeah, I don't give a *beep*. In the next couple days, I arranged to move back to our family's mobile plan and made sure my phone number (I ported my long-time number to the work phone) got ported back to me. I happen to have access to the company account so I was able to "approve" the port as I wanted to make sure it wasn't blocked. Took over 2 months before it was noticed that I was off the plan and when asked why, I reminded them .... and silence.
If I'm contacted after hours, I respond if and when I feel like it.
