I doubt the "average scientist" has views that are too different than mine on things like faster than light travel and when/if we will encounter and be able to interact with alien civilizations. But I haven't seen a poll, so who knows. However, I'm wondering if these physicists/scientists you read/listened to are average. I'm guessing you're talking about the media, which tends to grab fairly sensationalist personalities for their reports.
No I was really not talking about guys like Hawking or Kaku or other theoretical physicists/futurists, although the futurists are my favorites. But I was actually talking about the scientists that are just regular college dudes that I liked very much annoying and teasing them with my naughty semi-scientific/semi-science fiction questions.
I can foresee what's likely to happen in my lifetime, or at least I think I can. I'm 43, so basically half my life is over. I know how long--and how fast--things can develop, so I really feel pretty confident in projecting that far away. Especially in areas that I'm fairly familiar with... for example, I'll go on record saying that we won't have a usable (for e.g. code breaking) quantum computer for at least 15 more years. And maybe not even then. It's a HARD problem. Projecting 250-500 years is FAR more difficult, as I'm sure you understand. I hardly even venture to guess at what's possible in that span. And I'm just slightly more confident in saying what's impossible, although faster than light travel is one of those areas.
I asked as in more like guessing game rather than foreseeing. But I'm used to chat with physical science dudes, you guys tend to think in scientific methodology even when chatting with the average Joe like me.
As for the light speed issue, I agree generally. But on those kind of matters, it's more about the ground braking changes and discoveries in science to me. A lot of the current dominant thoughts in science can change dramatically in a blink of an eye, the history of science is full of that actually.
I have a distant relative who is also a physicists and I like his more open approach, when I ask him a question like "do you think this thing or that thing possible?", he always gives me the same answer more or less, "If I wanted to say something is impossible, I'd be a mathematician". Of course that's his escape answer from me but he believes in it at least partially.
Btw, I'm interested in quantum technologies on a popular science level so I know we have a couple decades more to see them in more applicable usage.
I'm not sure what you are asking about. Are you talking the ethics of genetics/biology? Or what I think is possible?
Haha, I know I suck at asking questions but fortunately you're good at answering, so I actually got most of the answers I wanted.
I do think ethical lines must be drawn, but I'm not sure where those lines are drawn. I think if NO lines are drawn, however, the potential for transformative technologies in that area is so great that homo sapiens could be unrecognizable as our same species in 500 years.
Is it a bad thing?
