TeX is a typesetting language. Like Postscript. There is no particular reasons humans need to write it. That is the reason LaTeX was invented (and Context). We need formats, like PDF or HTML, to exchange and reliably use informations and describe documents. TeXmacs is a document preparation system from the UI to all the other things needed, in one place, in a uniform architecture. It has its own internal format and it exports to TeX/LaTeX as it can export to HTML or PDF. Publishers do not need TeX to store documents, indeed TeX is no a particularly good way to store data. It is what it is: a typesetting language, not a document description format. So I do not see any conflicts between using TeXmacs and then sending a TeX file to the editor. Anyway in most of the cases them (or nowadays most likely you) need to reformat it to the standards of the particular journal. I (and many others, including the main author of TeXmacs) work in academia and I have no problem using TeXmacs everyday to do my work and then send to the publisher a nice LaTeX file, which I do not have to edit by hand. I'm (mostly) TeX/LaTeX free since 2006 and very happy about this.
