We are terrified, because we don't know, how to handle it yet. This should not stop us, the humanity. Our descendants will figure it out. There is no progress, if we are afraid of mistakes. The real problem is when we don't learn. Gattaca is a good example, what we should avoid.
FYI: I don't know if English is your first language but you are using commas excessively. All the commas in the first four sentences should be removed and the final comma should be 'of'. EDIT: Also, the second sentence should be "This should not stop us (humanity)."
Edit: Yes, this was not a perfectly warranted criticism. Yes, I may come off as smug. It's my opinion that needing perfect english should not be a requirement to have a conversation about tech in general.
I often get the feeling that in an academic setting every native English speaker assumes that everyone needs to be perfectly conversational in his English but when asked which other languages they even tried to learn you often learn that the English native hasn't put considerable amount into learning something else. Again, did not want to offend anyone.
I personally do not get offended, I like to learn. Still, I often experience corrections by an English native which are simply not called for.
