Will some bad things happen? Yes, like when humanity learned about atom fission. But the overall result is a net positive: lots of energy for everyone (and yes, that includes Iran) and no world war since then, even with major tensions like during the cold war.
As someone else said, there seems to be a curious wrapped view in the West that did not exist some generation before. Just even looking at old tv shows (Star Trek TOS) you can see people had faith that the future would be better. And the future kept its promises - lower mortality, longer lifespan, a dramatic reduction in poverty worldwide, etc. But the very few movies where you still see this positive stance are usually not made in the West.
For some reason it has fashionable to signal the future will be a dystopia. Sorry, no - there is no future, just what we are doing. If you do not like what you do, maybe do something else to make the world a better place? Or at least, don't complain about your own choices.
Fortunately, many countries in say Asia do not have the binders the West has. And please, do not say that they are "backwards" and will "evolve" their morals to see the light and adopt your own biased views. In my book, it's the West that's getting backwards and entering into some new middle age based on the new religion of environmentalism and naturalism.
Whatever. I personally do not care which country furthers humanity scientific progress, and I will take any advance as a "win" for team humanity.
