Or one can build an interactive dashboard to visualize their spreadsheet and make it pleasing. Again the expectation just changed. The bar is higher.
So far I have not seen productivity increase in dimensions with direct sight to revenue. (Of course there is the niche of customer service, translation services etc that already were in the process of being automated)
