1. Historical parallels in education technology

“As you might have imagined, there are a lot of parallels between this and the internet in the education wave. Just like RCA, MOOCs … let a kid anywhere access lectures from the best professors in real‑time, no longer limited by what's available locally.” — Bas‑12g

2. Early tech needed explanation and conceptualization

“It's fascinating to think that sound recording was so new it had to be explained. People needed examples of what someone would record or play back and why.” — dtagames

3. Every new technology undergoes a familiar explanatory cycle

“Every new technology goes through a period like this.” — dtagames (also echoed by rconti: “The original edutainment?”)
