What _has_ surprised me though is just how many companies are (or are considering) building 'internal' tooling to replace SaaS they are not happy with. These are not the classic HN types whatsoever. I think when non technical people get to play with AI software dev they go 'wow so why can't we do everything like this'.
I think your point 3 is really interesting too.
But yes the point of my article (hopefully) wasn't that SaaS is overnight dead, but some thin/lower "quality" products are potentially in real trouble.
People will still buy and use expertly designed products that are really nice to use. But a lot of b2b SaaS is not that, its a slow clunky mess that wants to make you scream!
I agree - it is surprising how many are looking at doing in house.
I think what they miss (and I say this as someone who spent the early part of his career outside of tech) is an understanding of what goes into maintaining software products - and this ignorance will be short lived. I was honestly shocked how complex it was to build and maintain my first web app. So business types (like I was) who are used to 'maintaining' an excel spreadsheet and powerpoint deck they update every quarter may think of SaaS like a software license they can build once and use forever. They have no appreciation of the depth of challenges that come with maintaining anything in production.
My working model is that of no-code - many non-tech types experimented with bubble etc, but quickly realize that tech products are far deeper than the (heavily curated) surface level experience that the user has. It is not like an excel model where the UI is codebase. I expect vibe-coders will find the same thing.
I have on several occasions built my own versions of tools, only to cave and buy a $99 a year off the shelf version because the maintenance time isn't worth it. Non-tech folks have no idea of the depth of pain of maintaining any system.
They will learn. Will be interesting to see how it plays out.
