Ask HN: Can Klarna Replace Salesforce and Workday with AI?

In the past couple of weeks there has been a lot of media coverage of Klarna CEO Sebastian Siemiatkowski's comment that the company is shutting down its Salesforce and Workday instances by leveraging "a combination of AI, standardization, and simplification".

The details are unclear and Klarna reference a "lightweight" tech stack rather than a complete move away from SaaS solutions, but do people feel it is possible to move away from these enterprise solutions or is this just marketing fluff from a company to justify large scale headcount reductions without spooking the market?
