I'm a native speaker of Norwegian, a language which also has three grammatical genders. I don't experience it as having to memorise genders. I only notice them when they are wrong.
The verb "regne" is ambiguous and the gender helps disambiguate ut.
Sometimes, the grammatical gender conveys information about the noun. Is it abstract or inanimate? Probably neuter. Is it alive? Can it move? Probably masculine or feminine.
Sometimes, when a follow-on sentence discusses previously introduced objects, gendered articles can clue you onto which objects are being discussed.
There are homonyms in languages with genderless nouns too, such as English, but context usually makes it clear.
It's hard to imagine a real-world situation where “it's raining” would be confused with “it's calculating” when stripped of the gender, for example.

That's the best argument I've heard so far, but it's so rare to require gender for comprehension. It seems a push to burden a whole language with gendered nouns for this purpose.
Regardless of the potential use for disambiguation, every noun having a gender affecting the articles and pronouns to be used adds a significant burden when learning the language. In some languages, like Spanish, the spelling of the noun nearly always indicates its gender, but this is not the case in German.
Acquiring a language as a native speaker in childhood is a significantly different experience from trying to learn one as an adult.
They're not completely useless.
"Det regner." - It's raining. "Den regner." - It's calculating.
