Hand Counting in your elections has been made illegal

On October 4, 2023, California passed a bill to outlaw hand counting in elections.
California must have a vested interest in how the votes are counted to make it illegal to Hand Count. This indicates that there is something very important in using electronic tabulators to count votes.? A big effort was made promptly to counter Shasta County's decision to hand count. Why should it matter? Could it be that there is a back door to these machines? Could it be the software as well as the device? I say this is a very strong possibility. Using either way of counting should be no business of the state. Why were Bernie Sanders voter upset in the California primaries? Go figure? If we don't get smart soon, I fear we will be slaves.
