A little python training in the python stack (pandas/numpy/matplotlib or other visualization libraries) can go a long way to simplifying tech stack and get rid of these mind numbing BI tools.

And companies are trying. Ex:https://www.bobsguide.com/articles/barclays-gordon-risk-mana...

But I also see spending more on these tools, in the name of innovation, because some bigshot likes tool X and that's what he wants to use. And guess what, now you also need it to be made available in the cloud.
