This is far from a comprehensive survey, though I think it shows that the net impact of technological changes is at least often and plausibly negative over the short term, and this changes to positive later on.
I don't think the above examples demonstrate this, because they don't provide a sense of the scale of the harm, nor do they weigh near-term benefits against near-term harms. Almost all technology has some harms? Refrigeration created CFCs. Antibiotics led to antimicrobial resistance. However, these technologies are widely considered to have been beneficial, even short-term.
The premise of your post is interesting, but the examples don't convince me.
