Gender is actually a useful layer of redundancy when listening to someone speak. If you miss a syllable or two you can fill in the blanks sometime if you caught the article.

Ditto conjugation. I actually like in Spanish how it's redundant if the pronoun is included, and alternately you can drop the pronoun for brevity.

For most situations, having the verb matching in person and number with the subject is enough redundancy. Conjugating also the gender bring the problem that every single thing you can name needs to carry a gender even if the concept of "gender" do not have any meaning.
