Also, to many people it has been very clear that this is just a product vision when they watched the video because I mention this multiple times in the video. I can understand that you would prefer the "hacker way" of first coding something before talking about it at all. Actually, this is what we did with edaviz.com During that work we came to the hypothesis that bamboolib might be even more interesting to many Python Data Scientists. However, we wanted to save our coding time because we might be slower than you. And thus, we decided for creating the vision video first. The landing page and the email addresses helped us to get in contact with users who are really passionate about the project and want to see it happen. However, the features within Jupyter are to some extent different than the features within Trifacta Wrangler which operates in the cloud. Also, the users of Trifacta Wrangler don't have the option to fall back to real code when they might want to.
