Third switch. 68000 series to PPC to Intel to Apple Silicon.

Now that they have stopped supporting Intel-based Macs, I understand the desire to not have to port new code and features to x86-64 to keep legacy apps happy.

That is why Intel-based Mac App support is going away, but Rosetta 2 as infrastructure will remain - a much smaller footprint of system functionality will be addressable by x86-64 code that they can reasonably maintain going forward.

That's actually better than where I thought we would be now - I thought by M6 they would remove the hardware extensions that allow Rosetta 2 function from Apple Silicon.
