My understanding is that voice interfacing is already the most common way to interact with a smartphone in China. Chinese (and other non-alphabetic languages) are notoriously tedious to type, and all sorts of keyboards have been invented to make it easier, but they all have a learning curve. Instead, it is far simpler to simply use voice recognition. Over the last decade many companies have pivoted their focus towards the Chinese economy, so a lot of the voice assistants, customer service platforms, and other software innovations we enjoy in the west are the direct result of companies trying to break into Chinese markets (and other emerging markets) with voice-driven designs that are accessible to billions of people for whom typing is an insurmountable friction.

Cliff Kuang and Robert Fabricant’s User Friendly is a really good book for learning about state of the art UI / UX design and the current trends that are likely to determine what our computer interfaces will look like in 2025 - 2030.

https://fuchsia.googlesource.com/ , Fuchsia - Wikipedia - Another really interesting project. This is Google’s new operating system they are building from scratch to replace Android, ChromeOS, Windows, and perhaps even server Linux. Fuchsia is being built from the ground up to replace the traditional desktop metaphor with a conversational or “story driven” metaphor instead. The ultimate goal is to be able to tell your computer in human language what you want it to do and have the computer do it. e.g. “Ok Google, open the survey results Sarah emailed to me. Ok, now plot a histogram with markings at each standard deviation, oh and a pie chart too. Great, save that and email it to Kyle.”

I’m not aware of what Microsoft, Apple, or any other tech giants might be working on, but Fuchsia is at least currently open source under BSD, MIT, and Apache 2.0 licenses.
