Do you agree that technology have many disadvantages to us?

Yes and disadvantages, like lack of privacy, added stress from an ever changing lifestyle, lack of personalization in services, jobs, etc. If it ever outgrows our wisdom it could very well be our downfall. You can now choose your babies eye color and we have the ability to clone humans and bring back Hitler, they are even trying to recreate a black hole in a lab despite being unsure if it can even be controlled. Too much of anything is not necessarily good.
