I am at a job where I am paid well to build software to do things in a distributed system that processes information across various external systems (some with physical world impacts). The outcome of that computing is revenue for the company. Using agent-wrapped LLMs makes the software authorship component of the job really fast. The rest is virtually the same speed.
For Thomas's mobile computing examples, these are done really well by my phone's operating system's built-in voice command system, mature for a decade by now.
At home, I use software that is well-crafted to do some thing. Or I write a series of scripts to do narrow things that for some reason aren't in Aptitude or Snap, for example "copy all the photos off my iPhone and rename them and sort them by date in my filesystem".
Perhaps I have no imagination, but I don't feel like having an LLM make applications on my phone. I want good software that someone that I trust wrote.
Thomas has been a successful cryptographer, vulnerability analyst, and entrepreneur, so he probably knows what he's doing. I just don't get it.
