It’s mind-blowing to me that the actual guy who designed it chimed in. Assuming it’s not a fake comment, what are the odds!?

Much greater than now, given the open discoverability of the original post here, versus the walled-off content we have today, locked away in discord servers and the like.

Furthermore, the act of replying to that post will have bumped it right back to the top for everyone to see.

That's why I like HN, it seems to happen a lot here! Mention a piece of hardware or software, even something obscure from years ago, and half an hour later you've had an answer to your question from the designer or the CEO.
