These days when project managers of new products seek my advice as a solutions architect I tend to suggest they create a minimally viable product that is written modularly so it can scale, but deploy it very simply on a few servers just like we used to 15 years ago.

Scaling is definitely a good thing, microservices make scaling easier, no doubt about that. But an MVP rarely needs k8s level scaling, it just needs to be written well so it can scale in the future.
