To be fair, today we have what we believe to be (much) more accurate models of how much computation a human mind is capable of and how long it will take to build computing machines operating at that scale. 36 years ago the argument that AGI was coming soon could be made in tandem with the argument that we'd make some fundamental advance that allowed computers to express intelligence with less computational capacity than humans (by orders of magnitude). Today we can make an argument that we'll achieve it (at least initially) by leveraging computational capacity on par with or orders of magnitude greater than a human mind.

Chances are that we're missing a very important piece of the puzzle for which there is no known solution even in theory. The problem is that there are many candidates for that important piece none of which have currently proposed workable solutions no matter what the computational budget or the accepted slowdown (they are equivalent). So I think some caution when throwing around projections numbering 'just a couple of years' is warranted, after all it's 'merely a matter of programming' but in this case we don't have a working model that we understand.

Maybe somebody who knows about AI can answer this for me: what do we expect of an AGI machine to be able to do when it "turns on?" How will you know it works? To compare to a human, you might say that it can cry, suck milk, and learn to walk and talk over the span of a few years, and then slowly, with a lot of trial and error, learn to do more.
