This is a cool event if you live in the local area. I haven't been to one in quite a few years - but back then they had a room where kids could make cookie wafers, play some xbox games, win some pretty good door prizes, etc.
With that said - if you think cool is looking through windows at large metal boxes without actually seeing what they do up close - then by all means it's COOL!

[I jest as I support tools in fab that we sell to Intel].
BTW - that video linked in the OP's post is nowhere NEAR what it's actually like in the fab - except maybe at 2am or on a Sunday afternoon
This is definitely a good video to watch if you're curious how fabs are built and what typically happens on a daily basis:

3:20 - 3:29 - looks like they are going to lunch and they show what the gownroom is like [you wear hoods, "suits", booties, gloves, and goggles].
5:55 - 6:43 is what typically happens in the fab on a daily basis [they don't show tool moves and the sheer # of construction workers walking around]. The inside of the fab is constantly changing - tools being moved around, FSE's [Field Service Engineers] repairing/upgrading tools/bringing in parts, etc.
