That's somewhat unfair.  I'll let Prof. Humbert explain his own
thinking, but I can imagine a number of pedagogical contexts where I
would use Python because it doesn't get in the programmer's way very
often, but require students to provide type hints as a compact (and
machine-checkable!) way of documenting that aspect of their design.  I
found his pedagogical approoach perfectly plausible when he posted
originally.
