> Video. YouTube. That's is the successor of Flash

Flash is interactive.

I'm assuming what they meant is that video has become the new "casual, accessible, vibrantly creative" medium on the internet, thanks to platforms like TikTok and all the powerful editing tools they include. Not a direct replacement but a spiritual successor

I agree, but it's sad that's the case. Media has become so passive since the rise of smartphones.

It can't be a full successor as YouTube doesn't do games.

Due to Web's failure to provide a proper alternative, everyone went to native mobile games.
