Thinking about Python Paradox [1], which language has interesting design and seems to have a bright future because it is drawing a community of "smart pepole" now?
My background is data analysis and Julia seems very enticing (I also think there is a lot of good design in R's tidyverse).
While python in 2004 was great, when I was thinking about it now, the adjective that I come up with is "tedious". It is my main lang at the moment though.
