Not necessarily. Using bytevectors and SRFI-4 vectors works very well for some kinds of data. Just, they aren't the best for other kinds (in principle they can work with all data if one is one implements a heap or other custom memory management inside one). They can be made to work but are hard for some types of data, and if you are working with pointers inside them very easy to get a segfault (even python numpy, which has a lot of work done on it over many years, still has a fairly easy way to segfault it if one uses object dtype).
