import asyncio: Learn Python's AsyncIO #1 - The Async Ecosystem

This series of videos introduces AsyncIO to Python programmers who haven't used it yet. The first episode is a high-level view on the async ecosystem. We cover: - why you'd want to use asynchronous code at all; - how latency drives the user experience; - what the difference between concurrency and parallelism is; - some of the problems you can encounter with threads, and with threads in Python in particular; - a short story about select, the OG of async calls; and - the history of asynchronous programming in Python that led to AsyncIO.
