I agree. Of all the UI crimes committed by Microsoft, this one wouldn't crack the top 100. But I sure wouldn't call it great.
I can't remember the last time I used the start menu to put my laptop to sleep. However, Windows Vista was released 20 years ago. At that time, most Windows users were not on laptops. Windows laptops were pretty much garbage until the Intel Core series, which launched a year later. In my offices, laptops were still the exception until the 2010s.
99.999% would be fantastic.
90% is not good enough to be a primary feature that discourages inspection (like a naive chatbot).
What we have now is like...I dunno, anywhere from <1% to maybe 80% depending on your use case and definition of accuracy, I guess?
I haven't used Samsung's stuff specifically. Some web search engines do cite their sources, and I find that to be a nice little time-saver. With the prevalence of SEO spam, most results have like one meaningful sentence buried in 10 paragraphs of nonsense. When the AI can effectively extract that tiny morsel of information, it's great.
Ideally, I don't ever want to hear an AI's opinion, and I don't ever want information that's baked into the model from training. I want it to process text with an awareness of complex grammar, syntax, and vocabulary. That's what LLMs are actually good at.
