I used to sell process control systems to the continusous processing industries.
The customers were ignorant and some treated our stuff like the Indians seeing Columbus's ships for the first time. Now the customers are very sophisticated.
On the road a lot, we used to know where every pay phone was that had a long cord and was in a quiet hotel lobby. Cell phones now.
It took a long time to prepare proposals, beause they were custom. We had to send them to company HQ to get prepared. Now everyone has a computer and a printer.
And, oh yes, at least half of my former customers have gone out of business. I'm glad I'm retired.
