And the future is not deterministic (or if it is, it is highly chaotic) so the existence of a thing does not have a simple relationship with what will happen in the future. Scientists who developed convolutional neural nets could not know how much good or evil was caused by image recognition technologies. The same technologies that are used to detect tumors in images can be used to target people for assassination.
There are exceptions, but my opinion is the supply chain of evil is paved with mundane inventions.
