Software itself is not inherently valuable, the value is in running and maintaining its data and any necessary integrations to other systems.

The bar for me to pay for a $10/month software subscription is pretty high, but once I make the decision that it's valuable, the actual cash cost is pretty low. Vibe coding something will never approach the quality of something that someone put enough thought and effort to turn into a product. The main place where I'll write my own software is when it's truly custom to my own needs, AI is a force multiplier for this type of work, but at the end of the day I still have very limited time to run and maintain a lot of custom software and data, so it's not going to cannibalize any of the SaaS I'm willing to pay for.

Obviously for younger software guys with more time than money, the equation will be different, but those were never the make-or-break demographic for SaaS anyway. I don't think the equation has meaningfully changed for SaaS sales due to AI, I see it more as continuously rising bar over the last two decades due to UX expectations, market saturation, limits on human attention and complexity tolerance.
