Is it feasible? Yes, absolutely. Are we anywhere near to 'human-level' AI? No, not by a long shot. How long will it take? Will we ever make it? Very hard to know.
Well... That definition keeps changing. For passed definitions we passed human-level a few times. And for some tasks we did or will pass it soon. So what is your definition of 'human-level' intelligence? Don't copy wikipedia; make one up in strict language (don't say consciousness please). For what a lot people make/made up we passed.
I'm not going by a definition. Getting an airtight definition is pretty hard. I'm talking in a fuzzy "You'll know it when you see it" sense. Sure, we get human or even superhuman performance at various constrained tasks, and that's great. But what about say, iron man's Jarvis? Still in the realm of science fiction.
We get superhuman performance on most tasks we use computers for now; people forget that easily. Not too long ago, before electronic calculators, we used people as calculators; it was a good job for which you needed a brain; they would consider computers now superhuman. A Watson hooked up to Asimo presented a few 100 years back (I don't think you actually would have to go back that far; my grandparents would not see it as less than human, probably more) would be considered god himself.
And we are on HN, mostly smart people here who vastly over estimate 'normal people'. It's nice that we (me included) assume a human can be taught to be able to do anything other humans can (with some margins), but for now this is not true either. And if we want this empirical evidence thing going on; if a (kind of) Turing test would be done with a large part of the population who have not been told they are, for instance, we let a human with earplugs walking around a village in Arkansas and walk up to an average person and play the human interaction for Watson (or something like it), it would usually succeed. It would in my village for 100% sure; I could actually make a knowledge based script for talking to a lot of people and they would not see the difference. So I understand what you mean, but I don't think in a chinese room kind of way (and that experiment, as many have shown, doesn't matter) we are not that far off. When we reach your level of input/output you will 'see it' but still, because you don't have a definition, will deny it. I would wager that we are there are already in the 'fuzzy' sense of at least 40% (I think it's a lot more) of the population. My grandparents, bless them, definitely think they are talking to a human when they call they book a railway ticket (which has been a steadily improving AI for a little under 20 years now); for their 'fuzzy' it's been solved and strong AI exists.
