With the advent of AI, a substantial portion of the laborious tasks involved in the 3-tier model will likely be automated, making it less likely for most to move away from this approach. In my opinion, the 3-tier pattern was established for valid reasons, and any attempts to simplify it by removing tiers might inadvertently constrain developers, leading them to eventually revert back to the original model.

Regarding solo projects, I agree that simpler stacks like BaaS or other innovations can be sufficient. However, fast-scaling companies often require the unparalleled flexibility and customizations offered by an in-house 3-tier model. This tailored approach ensures they can effectively meet the evolving demands of their growing operations.
