😠 Haters

“AI audio summarization tools may harm our ability to listen actively.”
To build active listening skills, use AI audio summarization tools to take notes rather than replace a genuine conversation with your friends, teachers and colleagues.

“AI voice summarization tools may erode our writing skills.”
If you use such tools, regularly engage in traditional writing to keep the nuances of written language.

“AI audio summarization tools have weak moats.”
This is true for most AI tools. But who says every product must last long? If you can make years of revenue in months, seize the opportunity.
