Users are experiencing inconsistencies and slower response times compared to the original Alexa, serving as a cautionary tale for companies like Apple, which has been more cautious in its development of next-generation Siri. The issues underscore the complexities of integrating AI into existing voice assistant ecosystems and meeting user expectations for reliability and speed.
