But the idea that a bipedal robot is going to be able to drive my work truck out to a remote & off-road site and go inside to replace a 9000 volt vacuum or climb up the 1800ft tower to find a loose hanger or air leak is almost as perposterous as the idea that we won't be using high power transmitters anymore. It just ain't gonna happen... And that's exactly why I left the datacenter to find a job like this one which requires hands-on skills.
There is a flaw in your vision of the future, let me explain:
If you watch old sci-fi, a dishwasher was a device with hands that poured soap onto dishes and scrubbed them. People imagined a clothes washer picked up the clothes and rubbed them against a washboard. Automated sci-fi planes had bipedal robots that sat in cockpits, automated sci-fi soldiers carried guns made for human hands. But we now know that this isn't how automation works. I work for a company that builds medical robots, and they do not look like people either.
At some point, some guy probably said "No robot will ever be able to unload these boxes from a truck, and take all the mixed-up samples from the box, stick on the barcode labels, look at each one to see if the liquid is right and if the caps are tight, carry it over to the centrifuge, and put the vials onto the vortexer, etc. That's crazy!" Well that guy doesn't have a job any more. We kinda joke that one day a microbiology lab will be a 5,000 square foot building with no human beings in it at all. That was considered skilled labor 10 years ago. Contrary to expectations, the cleaning staff will probably be the last ones to get replaced.
So lets look at your job:
* Drives truck: Already automated. (Tesla, etc.)
* Diagnose which part is broken: Somewhat automated.
* Orders appropriate part: Already automated. (Current project I'm on)
* Climbs up tower and replaces part: ehhhh...you win.
You have me on that last one. Replacing parts still requires a human. For now...
