I'm not so sure the narration is AI. Yes, it's a script and that may have been AI enhanced but I think that's an actual human speaking. The pacing isn't perfect, once in a while you can hear him take a fresh breath and once or twice there was a slight stumble in the pacing -- as if he was flipping to the next page. If it's computer generated speech then the algorithm is far more sophisticated than I've ever encountered before.
While I'm not "in the trade", it does sound very familiar and pretty much describes my home machine shop setup in 2026 -- reverse engineering broken or worn parts, layout and planning, prepping the machine and materials, bringing machines, materials and metrology up to temp first (especially in winter!), pads on the concrete floor, accumulation of swarf and smells in clothing, SWMBO's adversion to same, etc. etc. 100 years of tradition, unimpeded by progress.
I have a couple of 3D printers and a CNC mini-router. I have access to a decent size Tormach 4 axis mill and a 4 axis CNC lathe. Plus all the required software and computing power to CAD things and convert the resultant 3D renderings to g-code tool paths. They all have their place but the process is not nearly as satisfying and therapeutic as standing at the machine nudging the handwheels, measuring the results and fine-tuning the final pass.
Honestly, for hand-fitted custom repairs and replacements on old worn machinery, the old manual techniques are often faster and more efficient. CNC excels in reliably repeatable multiple copies of new parts, but for one-off repairs my go-to is usually the manual machines.
Just my 2¢
