Why isn’t Functional Programming the Norm?

# Notes

40:09 Why isn’t functional programming the norm?

• No sufficiently large “killer apps”
• No exclusivity on large platforms
• Can’t be a quick upgrade if substantially different
• No epic marketing budgets
• Slow & steady growth takes decades

41:01 Are OO languages the norm because of uniquely OO features?

• Information hiding (encapsulation) is not a uniquely OO feature. Modules can do it too.
• Inheritance is uniquely OO, but OO best practice encourages using composition instead.
• Without inheritance, objects and methods are not significantly different from structs and procedures.
