2018: How Do Engineers Choose Automation Today?

Posted by Arun Sinha on Jan 8, 2018 2:41:50 PM

It was really interesting, especially for those of us who lived through it, or some of it (I started college in 1985). Not to mention the great soundtrack, if you like 1980’s punk, new wave, and alternative music!
