Foundry work is very interesting of course, ie if you are building your own project in your own little environment, but I think that working under those conditions all day and every day, would sure change my mind!
The video doesn't include the dust and smells there would have been! - probably most modern type foundries will have a lot of improvements here and there, but all the development going on in China etc wil be creating a lot of wasteland, just as it did in America and Europe in the past.
