However, Winograd himself concluded that language understanding algorithms plus emulated bodies plus emulated worlds aren't sufficient to achieve natural language understanding.
Ok, but is this the correct conclusion ? It's pretty obvious that a SHRDLU-style simulation is not sufficient to achieve natural language understanding, but can you generalize that to saying that no conceivable simulation is sufficient ? As far as I can tell, you would make such a generalization because,
Every emulation necessarily makes simplifying assumptions about both the world and the body that are subject to errors, bugs, and munchkin effects.
While this is true, it is also true that our human senses cannot fully perceive the reality around us with infinite fidelity. A child who is still learning his native tongue can't a rock that is 5cm in diameter from a rock that's 5.000001cm in diameter. This would lead me to believe that your simulation does not need 7 significant figures of precision in order to produce a language-speaking mind.
In fact, a colorblind child can't tell a red-colored ball from a green-colored ball, and yet colorblind adults can speak a variety of languages, so it's possible that your simulation could be monochrome and still achieve the desired result.
A few notes about the site mechanics
A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
Once a post gets over 500 comments, the site stops showing them all by default. If this post has 500 comments and you have 20 karma, please do start the next welcome post; a new post is a good perennial way to encourage newcomers and lurkers to introduce themselves. (Step-by-step, foolproof instructions here; takes <180seconds.)
If there's anything I should add or update on this post (especially broken links), please send me a private message—I may not notice a comment on the post.
Finally, a big thank you to everyone that helped write this post via its predecessors!
