Sounds like it’s chemotherapy for neural network cells. “Probably won’t erase anything else since we’re targeting this here node in your sub-network from 1982...I would’nt worry, this won’t hurt a bit.”
Kinda like trusting Google or Verizon to only delete photos with a certain face on it. Might work, might miss by a bit.
If they can ‘erase’, they can ‘record’........................
