Yeah right. Specifics please.
Go here and look it up. I can give you examples I have been involved in of steel mills outfitted with modern continuous casters that produce more tonnage now with 700 employees than they did 30 years ago with 7000.
Of refineries, petro chem, and power plants that have increased production, reliability, and safety significantly over the last 20 years by applying advanced control systems technology. Look at design and engineering and understand the time to market and costs have dropped in major ways thanks to things like CAD and advanced modeling software.
Maybe to do live on a farm that is still plowing with mules, but if you haven't noticed the massive growth of technology driven productivity increases over the last few decades, you haven't been paying attention.
