Given PHP 8 has been released, does Hack provide enough value to consider it as an alternative? My take on it is no, but I'm curious about other people's opinions.
It is good to keep in mind that this article is more than four years old. I would advise against Hack at this point since most of the good bits have been integrated into the main PHP release - typing is a lot more predictable and enforceable for instance.
only played around with it briefly a few years ago. my view is "probably not unless you've already used it, or have knowledge of some specific PHP issue you know you're going to need that Hack provides". I think 4-5 years ago, there was a point where Hack might have been able to grow out of niche status, but I think that time's passed, with the growing community around 'modern' PHP and the ecosystem provided via composer and frameworks.
