Yup I think it’s best to leave credits and debits behind. We can use more than 2 bits these days.

I think a far more intuitive system is use negative numbers with a symmetrical accounting equation:

  Assets - Liabilities = Income - Expense

Then you always think in terms of:

- Do I have more or less assets?

- Do I owe more or less liabilities?

- Did I make more of less profits?

- Did I make more or less losses?

You can then use the accounting equation to check your reasoning. I go more into it here: https://news.ycombinator.com/item?id=40021375
