SaaS is dead. CsaS (custom software as a service) is the future. No. People will not vibe code their own tools. But the days of one size fit's all dashboards are dead. The days of "features" are done. All high level SaaS will be sold as custom 1 to 1 builds for each company that uses it. All low level SaaS will have functionality that allows you to ad any feature you need. The only thing that will matter is who has the best infrastructure and network to build on. Any company that is still trying to win feature wars with a universal Ui for all their customers will be dead in 3 years.
