I've seen a lot of statistics about programmers, but not specifically about Data Scientists or Engineers.
Because of that, I'd like to propose this survey:

1. Do you identify as a Data Scientist or Data Engineer?
2. What are the languages and frameworks you use the most at your job? Say, the top 5 or 6.

As a bonus:

1. What are the Frameworks you wish you were using instead?

I will write back with some visuals or analysis if this gets enough traction.
Of course all the data will be public here, so you can do your own too.
