And if you want a past example of scientists who feared their creation wanting to slow down, stop, or even undo it, BTW, let us consider the atomic bomb. Farrington Daniels took a poll of the Chicago nuclear scientists in 1945 asking what they wanted to happen with the atomic bomb. Remember that these were the people whose literal job was to make a weapon. Only 15% - 1 in ~7 - wanted the US to use it as it actually did, e.g. just start bombing cities just a couple days apart. Only a small majority wanted it even used in Japan, even against military targets without the Japanese first being invited to a demonstration in the US and being given ample opportunity to surrender. 13% - nearly as many as those who wanted the US to use it as it actually did - didn't want it used at all under any circumstance, in a war that had already caused a million American casualties.
The problem that they faced was that people like Groves** really wanted to bomb cities, and they, as the rank and file, didn't get a vote.
** - It seems dubious that Truman really understood what he was signing onto. While he never shirked from responsibility for authorizing it, the paper trail shows that he didn't seem to understand what he was approving at the time. In his diary before the attacks, he writes about the weapon, but about how he insisted it not be used against civilians, killing women and children, because he didn't want to sink to what he saw as the barbarism of the Japanese. In his first speech after the bombing, he refers to Hiroshima as "a military base", not a city, and says it was chosen to, insofar as possible, avoid the killing of civilians - but that if Japan did not surrender, then the US would bomb Japan's war industry, and then thousands of civilian lives would then be lost. Earlier drafts showed that it didn't contain the "insofar as possible" caveat. He genuinely didn't seem to realize what he was authorizing at the time. But Groves absolutely knew what he was doing, and deliberately selected sites for maximum civilian casualties. Truman seems to have come to understand what was going on by shortly after Nagasaki, where he gave the order to cease use of atomic weaponry, saying that the thought of wiping out another 100,000 people was too horrible and that he couldn't stomach the thought of "killing all those kids".
