Yes since version 1.0, it is quite good. I hope we can turn off these "AI" functionalities. I like my email chronology. I have my own filters to move emails etc... don't need or want an "AI" to do that for me.
We are in an hype fase. VC's pump money into it because it is the current hype, before this it was NFT's and crypto. The fase "AI" or a better name for it is LLM or GenAI will also pass. VC money will run out. There is no real business model yet that can support the enormous amounts of resources needed to train it and to run them.
Hardware is not fast enough yet.. it could be sustainable when it runs locally on my hardware. Till that time I see this as another hype we shouldn't pay a lot of attention to.
This and their AI thing they released a week orso ago, makes me considering another Email Provider. Not sure which one yet... They invested time, effort, and money in hype industries. No thanks. They could have used that time to make their core products (email, calendar, address book) better. My money went to the wrong things. :-(
