It depends on the company. In a certain sense, many SaaS products are more "software" than "service" and are therefore dead-on-arrival when competitors can undercut them or provide a local alternative. We've all seen the $10/mo AI inference apps that nobody uses, or the many transcription services that died with on-device NLP going mainstream.

So... AI accelerates the demise of stupid businesses and reinforces the value proposition of irreplaceable services. As a whole I would say that is a negative to a market that relies on "disruption" economics to stay afloat and continue raising capital.
