Big tech hiring ex-competitor SWEs is sus af or nah?

# Picture along, AMD hires this ex-nvidia dude who was expert in CUDA/Blackwell sauce for years. Now he’s cooking next-gen GPU or something Does AMD just accept and say “welcome king” or are they sweating bullets like “what if he still has Nvidia contact and can sell info to Jensen Huang for 100M USD cuz real talk: * you can’t erase years of secret sauce from your brain * NDAs are cute but we know the wink wink game same vibe with ex-Google at Meta, ex-Tesla at Waymo. We know that this Billionaires companies they dont follow the rules otherwise they aint billionare companies Are companies actually paranoid or is it just **“everyone does it, move on”?** Do they slap on extra spicy non-competes or put them on fake projects for 6 months? or am i overthinking and tech is one big happy family where secrets stay secret (cap)
