Everyone could build a SaaS before, it just is quicker and cheaper now because you don't have to hire a coder. The difference between success and failure is still building the "correct" product, for both meanings of "correct". For those who are unaware, meaning #1 is to build the product that the market will adopt, meaning #2 is to build the product correctly so it is sustainable and maintainable.

LLMs do not guarantee either of those, so unless they improve to the point where they do, this really doesn't change the overall market, it just changes the level of resources required to play.

What LLMs are going to replace is more likely to be the spreadsheets that departments run on, sharepoint and salesforce lists, and other such low-cost, low-effort, and legacy tools that departments tend to use for their own local processes.

You can build the correct product. The bigger issue is convincing people to take a chance on some unknown vendor. Besides no company or any size wants to or should depend on a lot of unsupported vibe coded internal slop. It’s no different than the old VB apps or Access apps

Anyone who thinks Salesforce is easy to replace hasn’t been part of large sales and consulting organizations - or hasn’t been close to sales side. Heck, even AWS’s internal consulting department depends on Salesforce.
