How much of Basemap is relevant to learn given that Cartopy is replacing it?

The entire section covers Basemap, but the official website states that Cartopy will replace Basemap.

How much of Basemap is worth investing time into at this point given Cartopy is being used now as well?

I understand that concepts can transfer, and in the end it’s about using a library to get the desired results. But it still has an impact on investing time into something that might not be relevant to the industry anymore.

Can anyone from Dataquest point out whether it’s still relevant to learn Basemap? And if so, how much of it should we really focus on learning?

Thank you.
