That’s kinda what I see when I look under the hood of today’s vehicles. What exactly is that thing?

It's an ASML 5500 series scanner. Basically a projector that uses UV light to expose circuit patterns on silicon wafers. It uses 2 robotic stages, one above for the glass "slide" (reticle) with the pattern being projected, and another below that moves the wafer under the projection lens.
The crazy part is the two move together with extreme precision (+/- a few nanometers) and speed. Most of the chips in your car, and many others we use daily, were patterned on these machines. 20 yo tech but still amazing. The new cutting edge ASML stuff is pretty much sci-fi alien stuff. Google EUV Lithography if you want your mind blown.
And yeah, I get the same feeling looking under a modern hood.

done, and mind blown...never fails to amaze how both friggin smart and stupid humans can be
Albert Schweitzer said sorta the same thing: “Man is a clever animal who behaves like an imbecile.”
I remember showing my youngest daughter how to write her first check...when she was 24 years old!

"Fancy rice cooker" lol, I'm using that, thanks. You actually understand this better than you think, since "scratches on rock" isn't off base. Etch is one of the major process steps where the patterns on some chip layers are actually cut using acids, or plasma.
Not to go too far down the silly analogy rabbit hole, but "waffle iron" would be more apropos, since ASML is a Dutch company (or, at least that's the country the suspected aliens decided to help - not a bad choice, actually.) That, or maybe a fancy "tanning bed" for computer chips. The trick being getting the bed adjusted right, while moving, in a focused image plane roughly 1,000th the thickness of a human hair. Side to side position is even tighter at a small fraction of that. I watch this stuff in action, put in process corrections measured in single digit nanometers, and still don't believe it works! Still fascinating though. If I was closer to mid-point in my career, I'd be all over learning that EUV stuff, but too much for my 60+ yo brain.
And agreed on above comments regarding the range of human ingenuity and stupidity. I used to think the instant access to knowledge, (including resources like YouTube) would be what raised humanity out of ignorance. Unfortunately the social media level of tech seems to have only served as a platform to fuel like-mindedness.

Totally agree, Youtube saved me a lot of money on repairs/replacements over the years by doing it myself. Dryer, washer, gas heater, car brakes replacement, transmission fluid flush, ignition coil swaps, etc.
It's also full of garbage, sometimes I hear my kids watching dumb stuff "hey! come on, you can do better!"

Finally gave up on glass shower doors and replaced them with shower curtains. Simply replace at minimal cost.
Yeah...you can get the glass doors clean with muscle and chemicals....if that's how you like to spend your time.
Etching: That came into my vocabulary in the early 70's when I made silver jewelry. Nitric acid etching. I studied the process, but never tried it. And before my time, there was the pick up line, "Would you like to come up and see my etchings?"

Judy, have you tried headlightrevolution.com ?
Better yet, there's a sub forum on the V6 F150 site that deals with Explorers since they share a lot of the same components with the F150. Plenty of links to parts and lots of videos.

And here I thought a box making machine was complicated
You work for Intel? I remember then hiring a few students out of my class for their fabrication plant down near Portland.

I did a long time ago. Started out as a Product Engineering tech at the Jones Farm campus... back when they made CMOS memory. Then later (late 90's) as on-site Field Service for SVG at the Aloha Fab. Had a few more changes before I ended up at a foreign owned fab here in SWW for the last 21 years.
i can relate. the electrician i have been using is a bit anal, and way overexplains everything. and points out the problem of his predecessors...
Thank you much for the suggestion, these turn signal lights are in the side mirrors.
