Everyone in 2019 was rushing to break their monolith into microservices. It was the gospel. The right way. The scalable future. We shipped microservices too. Across multiple client products — SaaS platforms, GameFi backends, Web3 infrastructure. And honestly? For a while, they worked great. Then AI entered the picture.
