Parker Ortolani blogs some initial thoughts about GPT-5:

I’ve been saying for about a year now that I believe the future of computing is software on demand. GPT-5 might just have made that a reality. It’s certainly at least the first glance at a future where that’s the case.

I’m not completely bought into this vision, where apps and UIs can be adapted on the fly, but I wouldn’t rule it out either. The screenshots from Parker are super impressive.
