Not really.

Another poster already give one reason why .tex files are not released  it's too easy to change them and claim that the file is yours.

Don't worry about (future) aiprograms ... by the time we have an aiprogram that can work with general mathematical concepts we should be able to have it read in .ps files (or we will have found something better.)

Fine. 'almost every' mathematician then.

No, it hasn't.

No. If you want to read a paper in a foreign language, knowing LaTeX will allow you to get the structure but none of the content.

Once you have a LaTeX document, there are MORE than enough programs to convert it to dvi, ps, pdf, etc. Theoretically, I could read a document in LaTeX and get the information from there ... but it would be MUCH easier to read the Postscript version obtained from that .tex file.
