I would agree with the statement that you don't need to know or write in assembly to build programs, but what you end up with is usually slow and inefficient.

Having curiosity to examine the platform that your software is running on and taking a look into what the compilers generate is a skill worth having. Even if you never write raw assembly yourself, being able to see what the compiler generated and how data is laid out does matter. This then helps you make better decisions about what patterns of code to use in your higher level language.
