Chris Lattner started working on Swift in 2010. He eventually left Apple to pursue other goals. When he found himself at Google, he pushed for Swift to be the next language used in AI and Machine Learning. This was an attempt to dethrone Python. Although Python is an easy language to get stuff done, its lack of static types and performance make it ill-suited for many things. I was quite disappointed when I saw that at Modular he will use a new language called Mojo. From its description:
Mojo combines the usability of Python with the performance of C, unlocking unparalleled programmability of AI hardware and extensibility of AI models.
I feel this is a missed opportunity to move on from Python.
