"Doing point A to point B in real world purely from photons to actions is much more profound than acing any AI benchmarks in the digital sandbox IMO. Most digital agents still could not finish a task from A to B without repeatedly modifying the prompts from humans despite well defined instructions deterministic outcomes and more compute. Here in the real world a robot needs to lug its own power supply facing unlimited number of uncontrolled agents non-deterministic environments in order to finish the dedicated task while the destination might be entirely ill-defined.

"Now the chip is so big is very hard to make. 28nm involves roughly 1000 process steps. Sub-5nm would double that. For every single step not going wrong would be close to miracle. When we (NVIDIA) taped out on 28nm a very stable node it still took us metal respin and few tries to get yield under control. A life-span of bleeding edge nodes obsolete very fast so fabs need every single second count to ensure it can recover the cost. Finally a) TSMC is very hard to get in regardless of degrees. Its not like they are specifically looking for PhD but undergraduate are not going to be taught how 3nm"

To remove the soiling while vehicle is moving we need to retain enough water in a very small area with high sweeping torque in a very short period of time.

We conducted several wind tunnel tests to study the fluid dynamic through various vehicle and wind speed then validate in the field close to million autonomy miles to understand the limit of materials and physics on self cleaning.
