Is the AI industry quietly running out of training data?

[SilverRider]

This report discussed something I rarely see normal users talk about properly: high quality training data may actually become limited.

That creates an interesting problem because AI companies rely heavily on huge datasets, but the internet is increasingly full of AI generated material itself.

Eventually models may start training on synthetic content created by earlier models, which sounds like a weird technological version of photocopying photocopies repeatedly.

Do people think data scarcity becomes a serious limitation for AI progress or will companies simply find new ways to generate training material?

The internet already feels flooded with repetitive AI generated junk honestly.

Future models training on that material could become a genuine quality problem

Companies will absolutely start paying more aggressively for premium human generated data if scarcity increases

Part of me thinks synthetic training data may actually work surprisingly well once models improve enough

This whole issue highlights how dependent AI systems still are on human creativity and human behaviour

[Craig]

The funny thing is that AI may end up increasing the value of authentic human content instead of destroying it

People talked for years as if scaling data infinitely was guaranteed.

Reality rarely works that cleanly
