The AI community is nowhere close to ditching Python. Most model development and training still use python based toolchains (torch, tf...). The new trends is for popular and useful models to be ported to more efficient stack like C++/GGML for easier usage and inference speed on consumer hardware.

Another popular optimisation is to port models to WASM + GPU because it makes them easy to support a variety of platforms (desktop, mobile...) with a single API and it can still offer great performance (see Google's mediapipe as an exemple of that).
