  - Can call you with a reminder, which can be more powerful than notifications
  - Works across platforms
  - Will eventually support more integrations, such as calendars, webhooks, and telegram/whatsapp/etc.

  - Phone call notifications have been quite powerful in practice. I miss push notifications all the time, but a phone call is harder to ignore.
  - More powerful scheduling: some filters aren't possible to create (like "last day of month") in the Google Calendar UI

  - Add a `proto` file covering messages that this Kafka consumer reads off the incoming topic
  - Pull in a gradle library for protobuf code generation
  - Add in a simple Kafka consumer and producer
  - Add a `Processor` that works on incoming messages
  - Hook everything up; the sevice consumes off Kafka, "processes" the data, and produces back to Kafka
