According to Soumith Chintala, Apple's actual engineering time on PyTorch support has not given him confidence that the PyTorch Mac experience will get close to NVIDIA's any time soon, if ever, source: Soumith Chintala on X, Oct 16, 2025. According to Soumith Chintala, Meta engineers are doing a large share of the heavy lifting to improve the MPS backend and feel responsible for the Mac experience, while Apple's priorities and engineering hours fluctuate, source: Soumith Chintala on X, Oct 16, 2025. According to Soumith Chintala, PyTorch has over 90% AI market share and Apple must prioritize full PyTorch software support if it wants Mac Studio to be an AI development box rather than mainly an inference machine, source: Soumith Chintala on X, Oct 16, 2025. According to Soumith Chintala, the NVIDIA stack remains the reference for PyTorch training quality versus Apple's current MPS pathway, which is a trading-relevant signal for relative AI development readiness between NVDA and AAPL ecosystems, source: Soumith Chintala on X, Oct 16, 2025. According to Soumith Chintala, he did not mention cryptocurrencies such as BTC or ETH, indicating no direct crypto market impact is stated in his post, source: Soumith Chintala on X, Oct 16, 2025.
