About the Least Powerful Abstraction

Imagine Andreas going around making annoying electronic sounds all the time.

Strike that. Andreas and Lars discuss using less power - less fancy abstractions - to make things easier to understand. Andreas likes to do a de-powering pass to code.

Avoid making something which is more general than is useful.

Lars goes into the lure of event sourcing - going for very high data resolution - it might come in handy! - at the cost of a lot of other things - how do we prevent duplicate user names?

You've got to love a JSON blob.

Finally, Lars derails Andreas' arrow of time and discussion of locking things down early when possible.
