My personal pain is Tableau trying to move uo the stack into data orchestration and compute. Code is completely inaccessible.
Not really a Tableau user, but I bet they are doing it to increase vendor lock-in. Which has always been an industry wide problem, proliferation of APIs and languages for that reason. I am not even sure how this could be any different, if the remuneration in a capitalist society depends on scarcity of the traded product or service (and the commons are privatized as a means to increase it). Here, the commons are the common understanding, standard APIs, and interoperability.
That said, if this thing is customizable enough, a good data engineer can prepare canned steps that fit the general structure of the customer data process and it may have its place.
ETL is hot again with machine learning. Companies have massive amounts of data they need to get in shape for models. The promise of a GUI anyone can use with little experience (low costs) means these tools are gaining traction again for the same lessons to be learnt from the last generation who moved on/out the industry.
