Posits would have been good if it was invented back when there was no standard floating point format. But it is not a tremendous upgrade from IEEE 754, which has lots of issues but so do posits. A customizable IEEE 754 would fare more or less equally to customizable posits, and AI workloads (especially for inference) shy away from floats nowadays because they need much finer control than what either IEEE 754 or posits can offer.
