Thank you, Automation Industry, for 30 years of employment

I gasp as I write this, but it's been 30 years since I was first employed by the automation industry.  I started out selling photoelectric controls (you know, same technology as garage door openers, with a light beam that you break, sending out an electrical signal) and from there progressing to vision and barcode systems, industrial controls, and finally, and thankfully, software.
