Historical context. Anyone researching the AI-video space needs to understand why Sora failed -- it's a case study in how consumer-pricing + compute economics can kill a product even when the underlying tech is impressive. If you're looking for a working video generator today, skip Sora and go to Veo 3.1 (best quality, now free via Google Vids), Kling 3.0 (best value, free 66 credits/day), or Seedance 2.0 (best workflow if you already use CapCut).
