I am not working with any of these tools. My main work environment is R with occasional Stan, and they work extremely well.
Well, one can always make the argument of not using specific tools or that one bought into the wrong system. Here's the problem though, everything I've listed worked perfectly on macOS with GPU acceleration at some point in the past. Maybe not out of the box, but with a few minor tweaks. Apple broke it all on their way to the M1. They created a Tensorflow fork which is a mess with most things not working properly or not at all. So they didn't deliver there either.
I had high hopes for the M-series, amazing chips. But the software or lack thereof makes it a little pointless except for daily tasks like reading/writing with low power consumption. They need to get their act together and deliver the software or open up the system so others do it for them. They've moved back to the PPC days, except it's a little worse. While many things were not available on PPC OS X, we knew what we bought into. With what I listed above, we already had our toys and Apple took them away.
I have no doubt basic R works on the M1, so does Chrome and Firefox. The big question is, how does GPU acceleration work on R on the M1? I don't know the current state of R, but I'd say it doesn't work. In the past when I used it, it relied on things like rpud, which in turn requires CUDA.
All of this could change of course, but I have my doubts it will. macOS and Macs are a niche market for Apple when it comes to profit. They make they money with iPhones, iPads, the watch and services/apps. The M-series is worth it for them, because it works in the Macs and in iPads/iPhones. My guess is, in 5 to 10 years we won't have Macs anymore. We'll have a hybrid OS running on iPads or some version of it and that makes sensor for Apple, because the iPad generates so much money and people won't look out of the Apple sandbox anymore.
