It may be worth watching the first few dozen streams sequentially, since most of the foundational ideas are introduced in those episodes. And then from there, you can browse for specific topics using the episode guide as they become relevant to you.

For one thing there are like 500 episodes that are roughly 2.5 hours each, that's 1250 hours - there's a major opportunity cost there.
The streams were 1 hour until episode 350, when they switched to 2 hours. So the total time cost is more like 650 hours, plus Q&As which probably add another 100 to 200 hours. So if you watch at 2x speed it's around 350 to 400 hours. A smaller undertaking, but still not at all worth it to watch the whole thing in my opinion.
