Highly, highly recommended for anyone who wants to actually understand linear algebra. If you're studying the material or need to use linear algebra in applications or are just curious watch those videos. It's not a huge time invest and it's a huge "force multiplier" to actually have an intuition for what's going on under the hood instead of seeing things as just collections of numbers and magical sequences of operations that "do stuff" for who knows what reason.
