This feels a lot like the old RPA hype cycle to me — more sales narrative than structural change.

Most companies are not going to replace stable SaaS with a pile of AI-generated internal tools. They don’t want the maintenance or the risk.

If there’s a real B2B game changer, it’s Microsoft.

The day Excel gets a serious, domain-aware AI that can actually model workflows, clean data, and automate logic properly, half of these “build vs buy” debates disappear. People will just solve problems where they already work.

Excel has always been the real business platform. AI will just double down on that, not kill SaaS.
