A 4 year old device on a different CPU architecture. The Mac Pro wasn’t a device aimed at developers, it was aimed at creatives. This title is grandstanding.
There is no actual technical limit here, only a typically inconsiderate policy one.
Any architecture may produce any collection of bits for any other, and even run them and test them. Every m1 user sees this every day when they continue to run intel apps.
Would be a good machine for data scientists as well, but those usually prefer cloud instances that reside near the data rather than bringing the data to the workstation.
