There are a few key properties of Python that make it a really great language to develop in, especially at the start of a project: no need to figure out type annotations up front, high signal-to-noise syntax, and Python's absurdly dynamic nature. These all work together to speed development, especially the early stages where you're modelling the program's design. As the program gels, then it becomes a much better time to nail down precise data types and then 99% of Python programs no longer need an extreme level of dynamicity (dynamicness?). So far, Mojo seems to be getting this right: stay out of my way when I'm roughing things in and rapidly iterating, and then if and when it's needed, I'll happily lock in data types in exchange for more speed, AOT compilation, getting onto a GPU or microcontroller, etc.
