Could it just be the Dunning-Kruger effect in play? it takes a while to realize how much you don't know (some don't stick around long enough to realize that or lack the self-awareness and self-inquiry)
I recommend looking into re:dash, which is an amazing and widely used data collaboration tool for your data. Arik Fraimovich is doing a great work with a growing community of contributors.

Disclaimer: I'm the founder of EverythingMe, re:dash was born in one of our hackathons but have since become its own beast.
Some background - we (engineering at EverythingMe) wanted to turn our organization profile on GitHub into a showcase of our open source work, so we built this tool and open sourced it for other to use.

I might have taken it to the extreme (always a good discussion kick-starter), but aamof we did try Tableau an a range of other tools, and being a startup that uses data and most if not all of its people are OK with SQL we managed to be a lot more productive and transparent with re:dash.
There's a blog post about the motivations behind building it here - http://geeks.everything.me/2013/12/05/introducing_redash/
I totally agree, columnar databases have rendered "traditional" BI tool irrelevant and required the analysis and visualization layer to adapt to billions of records accessible via SQL.
We (EverythingMe) open sourced our own internal data visualization and collaboration tool which is used with our own Redshift setup - https://github.com/EverythingMe/redash
