In 2005 or so, I got a tip about an application called LaunchBar, which would later be copied by Apple to replace the Sherlock search tool, and later by Microsoft in its PowerToys suite. The machine learning LaunchBar used to tailor its responses based on my previous behavior was life-changing. Instead of configuring an application, I just had to use it to change how it behaved.
This is how language models and AI are going to improve your products. Subtly. Behind the scenes. Slightly improving a thousand different use cases, only a fraction of which your regular usage patterns are going to intersect with.
I have never been so glad that I talked myself out of buying the new iPhone this year! Siri is the primary input method I use for my iPhone. I would say I make around 20-30 vocal requests a day. It will be so nice to be able to do things like create a meeting on a calendar with a conversation instead of having to frame the request in a single sentence! I hope they do this rollout well.
