Blame? Oh, there is sooooo much blame to go around.
We can blame the dunderhead who made the tool, for not considering the knock-on effects.
We can blame the greedy executives who chose to try to make profit off the tool at the expense of those harmed by it.
We can blame the shoddy tool for being a piece of junk.
We can blame the thoughtless person who uses the tool, for willfully adding to the suffering in the world.
But, in the end, if you want to keep people safe from harm, blame isn't constructive! Understanding the situation, and putting well-considered controls on the tools, the people, or both, may be constructive.
