- Latency is too high for ultra performant backend systems (99th percentile for max latency)
- Early on it made it quick to iterate, but as the size of the team scaled the developer velocity started to slow down
- Microservices enforce a tight interface so having static typing enables large teams to catch issues earlier. It really has an impact with 100+ devs.
- Quick to learn, but easy to write poor quality code
- Enables you to move fast, but allows for sloppy code
