What stands out for me is that the productivity gains for small and medium-sized enterprises are actually negative. But in Germany, for example, these companies are the backbone of the entire economy. That means it would be interesting to know how the average was calculated, what method was used, what weighting was applied, etc.

All in all, it's an interesting study, but it leaves out a lot, such as long-term effects, new dependencies, loss of skills, employee motivation, and much more.
