Will older M-series MacBook chips not support personalized Siri?

Siri is looking to get more advanced in just one month, and I can see Apple setting hard cut offs for the new revamped Siri only working on newer Apple Silicon with better processing capabilities and with more than 8GB of RAM.

The main feature that I believe will set this cut off is the long-awaited personalized Siri. It definitely sounds resource intensive with its on-device processing, but as a current M1 Air owner, I hope I’m dead wrong about this. It’s a good thing I’ve kind of swapped devices with my wife who is (or was) running an M1 Pro with 16GB of RAM.

Currently only the MacBook Neo sits at 8GB of RAM, but for the price point it’s justified. Next year's iPhone 18 is also rumored to get a spec bump to 12GB of RAM, so that might be the new minimum to run more advanced Apple Intelligence features.
