The metaphor that’s popped into my head recently is baking bread.

You can learn to bake good bread. It’s not _that_ hard. And it’ll probably taste better than store bought bread.

But it almost certainly won’t be cheaper. And it’ll take a more more time and effort.

Still, sometimes you might bake your own bread for kicks. But most of the time, you’ll just buy the bread someone else has already perfected.

Baking bread also takes hours of waiting.

I can have fresh bread anytime I want from a handful of nearby stores.
