Its a science fiction trope, perhaps a trope in real life as well. Brilliant scientist gets paid to work on potentially dangerous thing. They know it is potentially dangerous so they warn about it and are reassured over and over again that nothing will be done without their consent, or that things will be done with the utmost care and security. And then scientist finally succeeds in creating the thing and the business owner's greed takes over and releases it in a premature way.
