I have to ask because people here keep talking about cron’s speed:

What functionality of a calendar is speed dependent? Genuine ask and not trying to be snarky, speed just hasn’t ever been something I’ve ever had to worry about with a calendar tool so the notion (pun not intended) is merely a foreign to me personally.

Is it opening events? Creating a new calendar item? Syncing, or something else?

Where is the speed gained in from compared to Calendar.app?

If it's anywhere close to the speed of Calendar.app it's super fast compared to Google calendar, maybe that's what people are comparing it with. Remember that the Windows software ecosystem for basic tools is terrible, so maybe its users are the most excited.

Ok but what is being measured? What functions of the calendar app are being proclaimed faster than…?

That’s the thing I’m not growing here and sorry but the answer above doesn’t tell me this

These are all nice features, but hardly deserve the qualification "next generation".

Do you disagree with Coca Cola calling coke “the real thing”, too?

It’s marketing. Read the qualification as “good”, and trust it as much as any marketing.

>Do you disagree with Coca Cola calling coke “the real thing”, too?

Yes.
