You claim you just inferred sounds from letter shapes and started putting it together yourself, with no training data?

I remember just looking at the pictures, and for some reason I really liked Spiderman. (There was a Spiderman cartoon in the late 60's.) I noticed that Spiderman's comics when they showed him in his ghetto apartment, it was always filled with books, with the titles readable. I could not read the titles, but figured if the people making the comics were putting all these books in Peter Parker's apartment, the books are probably useful for superheros. That idiot logic is what got me to start wanting to read, to know what Peter Parker was reading. I started, slowly, and taught myself with a goal.

Are you implying that people use “training data” to learn things

I am joking with the terminology, but I don't believe B.S.'s claim that they were able to do human language learning without 'labelling'.

It's a valid way to learn a second language in the same script, see Lingua Latina for example, but how can you possibly learn a first language or a new script without being told the sounds characters make? You can learn to listen/comprehend and speak by in immersion like that, but not reading & writing.

I think he's implying that humans require available information from which to learn new things, and that borrowing a term from AI research is one valid (if backwards-sounding) way to describe that fact.
