How should we design AR Systems? Better Abstractions 

System Design Principles Distributed Systems ● Decrease processing time ○ Co-location ○ Caching ○ Remoting ● Sharding ● Scalability via concurrency ○ Pooling ○ Parallelization 

System Design Principles Distributed Systems ● Decrease processing time ○ Co-location ○ Caching ○ Remoting ● Sharding ● Scalability via concurrency ○ Pooling ○ Parallelization AR Systems ● Real time by default ○ Efficient networking ○ Response time ● Many devices ● Concurrency to take advantage of Many cores ○ Lock free programming ○ Actor models
