> Google having TPUs in its datacenters that do work that cannot be reverse engineered Help me understand: TPUs cannot be reverse engineered because the user doesn't have access to the physical device, but other devices like GPUs can? Can you show some examples of reverse-engineering of GPUs that has been performed on the basis of having physical access to the dies? Are you aware of any reverse engineering done on them using other means? How much has this reverse engineering prevented e.g. NVidia from being financially successful? Finally, since patents are freely available to the public once they have been granted, does that nullify some concerns regarding reverse engineering? I'm not an entrepeneur, so take this with a fistful of salt, but having worked at places like NVidia, I would never try to compete head to head with them, as a startup. Very few semiconductor startups achieve any success, and the ones that do start by finding a very particular market niche where the established players aren't even trying to play. Again, I wish you good luck.
