In Jordan's new video on Etherloop he gets a lot right, but also misuses some standard terms (which is fine and maybe easily overlooked or benign)
Very short summary on the Etherloop: Generalized redundant hardware with guaranteed virtualized specific and unique necessary dynamically allocated resources.
Another way to say it: Two identical Etherloop compute hubs which are, in effect, like data centers or virtualized compute clusters.
Or another way: Take all the uniqueness and differences of the controller hardware and instantiate it into software or simplify the design to work with existing software.
Or think about it like an equation: Add up all the compute of all the controllers, all the memory, networking and power needs, redundancy, control loop, stability and reboot cycle time requirements. Take the lowest common denominator of all those and build one hub to operate and meet those requirements.
This looks like a data center, with a server, that instantiates a set of virtualized resources, managed by a trusted hypervisor, that boots into dedicated resources, with a dedicated operating system, which can execute commands with guaranteed results.
Why do this? It enables unboxed, saves a ton of money on hardware, cuts down on weight, manufacturing time, allows for all issues to be software issues thus allowing for faster break/fix cycles.
Why hasn't this been done before? You'd need to first have the vision of doing this, hire the right people and put a crazy amount of faith that it could be pulled off as it is a boat load of software engineering at the lowest levels of compute.
Etherlopp is great, much better than can from bandwidth perspective.
In house controllers are awesome , software defined vehicle ftw ... BUT
Seeing the video I was thinking how much effort would it be for Ford to "just license fsd" for a future fortd car.
Tesla is on a hole different hardware and abstraction layer than the hole industry - which is awesome, but does this mean fsd is exclusive as of dependencies?
Explains a bit why cybertruck fsdb was late, the architecture is vastly different than the can based cars before ....
Just food for thought
