how close are we now to being able to plug in an eGPU into an Apple Silicon device?

  It might just work, eg here's a tryout on another arm platform where it seemed chipset bugs were the main problem : https://www.jeffgeerling.com/blog/2022/external-graphics-cards-work-on-raspberry-pi https://www.jeffgeerling.com/blog/2022/external-graphics-car...

  That's two completely different things. I'm not even sure if the required hardware elements for eGPU - namedly, a "back transport" of rendered frames via Thunderbolt and shuffling them directly to the screen - are there on M-series machines.

    Usually you plug the eGPU into a monitor directly instead of backfeed it to the built in display. The bandwidth is already low enough without showing rendered frames back across the link too. There are some limitations on the PCIe/Thunderbolt but Marcan has written a few times he thinks it may be possible though probably not worthwhile from a performance perspective. Of course even base thunderbolt is a WIP at this point so that answer could always change.
