My answer to the deleted comment and to this.

It is a bunch of incremental improvements to the Python like language environment.

That's no big programming language advance to me. A biggie would be to Haskel or even Rust.

That's not to say it won't be wildly more successful as it gives a lot of what people want in a number of areas all in one go.

I'd jump on board except for the vibe around the current licensing. Maybe that will change and I'll be one of those Rust people who comment 'but Rust' on every C and C++ article, except I'll be saying "but Mojo" :)

Hard to remember the last language that felt so obviously sold by something other than an actual community. Even Swift tried its best to exist outside of xcode and mac/i os

EDIT: perhaps I'm being too harsh—this was literally just announced. I'm just taken aback by the blatant marketing as everyone else is.

Swift isn't trying anything, Apple only cares about their platforms.

Open source Swift is as relevant as Objective-C was, never expect any big uptake if none of the key frameworks is open source.

Outside Apple platforms it only fulfills two goals, being good enough for Apple and iOS developers to deploy their server code on GNU/Linux, a bit of goodwill marketing, and that is about it.

I meant only that occasionally I run across someone who fervently believes in bringing Swift to other platforms or even just outside the Cocoa/UIKit/whatever blob. It is very reminiscent of Apple's half-assed promotion of Objective-C outside their investments, I agree, but both languages had communities pushing for expanding their usage well outside the corporate sphere. Small communities, but easy to find.

There was v lang in recent memory which made grand claims.
