Most of the time, liability for defective software should be civil liability in tort or contract. In most cases where something bad has occurred involving software, it’s going to be hard for the developers of the software to have the sort of mental state and unattenuated causal connection with the occurred harm that we typically require for criminal liability for reckless conduct.
I’m not saying it can’t happen, but it would be very unusual circumstances, especially since there’s usually an operator of the software sitting between the developer and the person harmed by the software.
