Dropped some knowledge bomb on some new-ish Go folks with the interface implementation compile-time check hack.
```go
var _ TheInterface = (*TheImplementation)(nil)
```
Minds were blown.

The most important thing you can do when building an HTTP API is to define a json error response body and unique response codes.
HTTP status codes are *not* sufficient.
Clients need more detail to provide a good UX for users.
There are a million things that can cause a 400 Bad Request, for example.

If game devs can say "just use Unreal/Unity" to build games then I am always going to unapologetically say "just use Go and PostgreSQL" to build your backend.

I really do not like that the only way to train and plot data is monopolized by NumPy and MatPlot in Python. It's so damn slow.

On a call today with a group of folks shooting the shit before the meeting started...
Producer: "I just turned 22 a few months ago."
*a moment of silence*
Me: "In a few months I'll be 22 years older than you."
Things I didn't expect to ever say in a meeting. I feel old.

The 2 outcomes I see for my career with AI:
1. It all collapses and I cash in cleaning up the mess at triple my hourly rate
2. It takes over my job and I retire from tech completely and go do something else
Either way, I win.
