We use Place-Oriented Programming (PLOP): we know location of data in memory or database and use that to update it.
This paradigm comes from the times we had really limited RAM and we had no other way to program. This was the only way to do programming.
Since that times, the capacity grew million times bigger.
When a thing grows a million times bigger, almost none of its characteristics remain. But we are still clinging to the Place-Oriented Programming.
If we look at memory and records before computers, we see that they do not work by rewriting information.
Memory does not work by replacing the old information.
Records are usually append-only. If you make a mistake, you add a corrective entry (e.g., you don’t alter old records in double-entry accounting)
Values are immutable
values can be shared (because they are immutable, this is safe to do)
easy to fabricate (in the sense of meta-programming. you can produce the strings, lists and maps in every language. i.e., generate)
values aggregate values
