How Biology Solved Efficiency First

(And Why Systems Keep Catching Up)

The Pattern

The most efficient systems we build almost inevitably mirror biology. That is not coincidence. It is because biology already solved the hardest problems under the harshest constraints.

Postal systems led to networking because both solve the same fundamental question:
➡️ How do I reliably get this payload to that recipient through an unreliable, noisy medium?
Humans solved it first: addresses, routes, handoffs, retries. Networks followed the same model because it works.

	#Step 1: Get a list of all alarms in INSUFFICIENT_DATA status
	#Step 2: Get a list of all instances (stopped and started)
	#Step 3: Find all alarms on instances that don't exist, and delete them

	#Step 1: Get alarms in INSUFFICENT_DATA state
	###################################################
	#The max that we can get per loop is 100; all alarms for nonexistent instances will be in
	#INSUFFICIENT_DATA state so let's just go through those.
	insuff_alarms = []
	loops = 1
