My comment was satirical in nature. SLAM is an interpretation of what the parent comment had described:

There is a general pattern of statements of the form "We'll only really have AI when computers X", followed by computers being able to X, followed by everyone concluding that X is just a simple matter of engineering like everything else we've already accomplished. As my AI prof put it, ages ago, "AI is the study of things that don't work yet."
Which is exactly what we do with many kids today; makes you wonder how many times we might invent AI and not know it because we don't raise it correctly so it appears too dumb to be considered a success.
