“Embodiment” is most important for 2, and to fool humans into thinking you are a real human (as in the Turing test), able to talk about the human experience and relate to other humans.

Animals (including humans) are born with a version of 3 (and 4). Emotions are simple. Thought-level nuance is learned over time, but data learned by one android (or whatever) can be shared. Also, children are able to learn from comparatively few data points, and computers are beginning to do this too (see “one-shot” learning, learning from one occurrence, like the way kids sometimes pick things up).

If you make a child android that looks and acts like a child, people will read to it and play with it; there are movies about this! :)

It would take a lot for a computer to write a beautiful novel, say. But not to appreciate and create beauty in other ways. And I really think computers could write some excellent jokes along the way to becoming more human. Pretty much anything they learn to do can be used for comedy. Physical movement with “character” gone wrong leads to physical comedy. Common-sense knowledge leads to common-sense comedy (like the joke about the elephant leaving tracks in the butter dish, which kids of a certain age find funny but adults seem to have grown out of).
