One thing Apple is good at is waiting until the market is ripe and then releasing a better product. Like mp3 players, phones, tablets, etc.
Except Siri keeps getting worse every year. In terms of actual usefulness, connectivity issues and plain old voice recognition.
And it seems to not be just Siri. Every Alexa device in my house has gotten more deaf and more stupid. But yes Siri has declined recently I agree.
All my echos went out the window as soon as they started with product promotion
