Interesting comment in the article about how VB is still being used in some organizations. One company I worked for ran some critical business processes in Excel + VBA. I hope they've moved on from that. I imagine there's a lot of that lurking in Fortune 500 companies.
In engineering companies, Excel + VBA will never go away. Most engineers who are not CompE or CS folks really do not want to program. Excel is powerful for nonprogrammers, and the allure of automating some of it with VBA is almost impossible to resist. Excel gives you a platform where you can feed in numbers, do some calculations with a click of a button, and produce charts - all in one file. And it's trivial to tweak if you need to change something. An engineer with little programming knowledge can be "operational" quickly, and the "tool" is safe to pass around to customers.
I had to live with this for a few years and hated it. Fortunately, the Ipython notebook (now Jupyter) and Pandas came along, and to some extent I managed to stop using Excel.
