Was a "joke" since Elon being a clown on "the specific platform". But this design is absurd since "there is already profound high-bandwidth low-latency packet-based protocol for inter-chip networking (PCI-e)" and "This is terrible to run on conventional Ethernet/II infrastructure due to lack of hardware acceleration support due to lack of checksum/etc. offloading support".

I really think there is no performance enhancement, heck even worse performance when it is being used on data center deployment until they decided to design their own switch on everything. and considering everything and the packet header is being about the size of about UDP, It seems there is no advantage of using it instead of UDP with Broadcast IP addr., Maybe in their hopes and dreams, Broadcom or other chip vendors might support their ethertype but It will be further in the future.
