You're being downvoted because saying it's some imitation or reinvention of Lisp is a gross misrepresentation. Pharo's lineage takes it back to Smalltalk-80 beginning in 1976, at the very least.

If I remember correctly at least Alan Kay openly admits being very inspired by Lisp. Unfortunately the limitations/walled gardens they chose to impose in the name of simplification, everything is an object etc, had us running in circles for a long long time. My guess is it was picked up by managements for the same reasons as Cobol, Java, Go etc.

Well it doesn't say that. I just said it sounds like a reinvention of Lisp because that's what it sounded like to me from what it says on the homepage.

Actually, its an IDE for modern “Smalltalk” development. Pharo has a few extensions vs Smalltalk-80.

It is a little odd that the homepage doesn't say Smalltalk on it anywhere.

It says seaside at the bottom, which is a well known framework for it. But, yeah, they could do better.

Pharo doesn't call itself Smalltalk but a language inspired by Smalltalk, but that's a matter of fairly arbitrary line drawing.

I wonder if there's something akin to the thinking behind the renaming of PLT Scheme to Racket going on.

I guess you're trolling

Trolling by asking a question to which I wasn't able to find answer after a good few minutes on the website?

I'm not sure "trolling" is fair, but perhaps phrasing your confusion more as "the home page doesn't give me a very clear idea what this is," which is true; the actual front page doesn't mention Smalltalk at all. I suspect that they wrote it with the expectation that nobody just "ends up" on the Pharo web site without having some idea what it is already. Under normal circumstances (e.g., not being linked from the front page of HN) this is probably a reasonable assumption, but it couldn't hurt them to have something like what Squeak.org has: the first full sentence on its home page is "Squeak is an open-source Smalltalk programming system with fast execution environments for all major platforms."

Having said that, how few minutes qualify as "good"? Because if you click "About," that page has a heading that says "Pharo features" whose first bullet point reads "A dynamic, pure object-oriented programming language in the tradition of Smalltalk."

It still doesn't say what the purpose of it is. I don't really expect it to either. I expected that asking the question here would be OK, though.
