Wouldn't Julia be that language? Its fast, supports static typing, and is built from the ground up for machine learning/ data science. It also has a built in REPL.

Julia is that language now. Previously I had sunk cost fallacy regarding Python, but now we are building a brand new application from scratch, and we chose Julia.

Julia is nothing like Python though, and it has other flaws like 1-based indexing and huge delays loading packages as it compiles them.

How is it nothing like Python?

1-based indexing is definitely not a flaw. And version 1.6 massively decreased package import and precompilation time.
