From their profile, this person makes a living selling AI programming products, by the way. Who could have guessed. There's a pattern to be noticed, even.
Who’s “this person”…me? I don’t make a living selling AI programming products. I make a living building knowledge systems, mostly around search engines and data wrangling.
Whether that person is talking their book or not, there absolutely has been an app explosion. Github & the app stores have all reported as much over the last year.
I also have repeatedly experienced the phenomenon of nontechnical people having built custom software to run their businesses. A lawyer friend was first, sending me a link to his GitHub(!), where he has built a custom client intake/practice-management application to work as the firm works. He's not the only non-technical lawyer I know who has shared vibe coded apps with me.
I personally build many, many single-use apps than I ever would have before. Gnarly debugging sessions can be greatly simplified by inserting a custom piece of disposable tooling/etc. I am not a Mac programmer, but I now have custom Mac apps to solve problems that only I want solved. Do these count?
Honestly, I would be a little surprised if anyone posting on HN did not have some personal exposure to the explosion of apps.
