Heh, nice video, though I have to comment on the outdated hardware. I've seen many factories with 30+ y.o. hardware and hasn't been updated as it runs already for 30+ years. The software and hardware has no errors. Every bug the software or hardware had, has been debugged. People really have no idea how many troubles they can get into by upgrading and there is too little to gain, so for a factory where continuity is vital, it's an absolute no-go. Heartbleed, for instance, was a security vulnerability in OpenSSL because OpenSSL was updated with added functionality, heartbeat, which contained this error. In other word, an un-updated OpenSSL was more secure.
