The most important aspect in the early sci-fi visions of computers was that you could trust the answer the computer gives you. Futuristic sci-fi computers were, and are, DWIM[0] - they understand what you're asking for, and give back as accurate and relevant answer as possible. This is in stark contrast to real-world search engines and voice assistants of today: sure, they can tell you a lot of things, but half the time they can't parse your query correctly, and the results depend less on their accuracy, and more on who paid more to get their stuff in front of people (relevant or not). Second-guessing and sanity-checking answers are a standard part of our interactions with query-based interfaces. So we have a lot to go to match even cheesy robots from pulp comic books.
But we sure as hell nailed the glitter.
