And he appears to have died on his birthday?

The official cause of death is listed as natural, and Conrad remembers hearing that the MRSA had stopped Kleiman’s heart.

EDIT: but I cannot find David Kleiman's name on the page

you're right! nothing.

so what does it mean? he is still alive?

...

I don't think so, unfortunately.

Kleiman's co-workers, Paige and Conrad, were interviewed by Gizmodo and I think we can trust their words untill now.

I believe the closest we have to Satoshi these last years, is this: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-August/010238.html

That particular email is not known to be hacked (but we can't say for sure that it isn't), there is no spoofing involved, and he also had to register and verify the email to the mailing list:

The writing style and essence of what is written does not have any troll like qualities like the spoofed "I'm not craig wright, we are all satoshi" message that appeared a few months later. The August one isn't spoofed, it is serious and consistent in writing style, while also trying to "sneak in" some comment of concern for bitcoin itself - as far as node incentives go. Kind'a like, since I broke my silence, let me also say this that is bothering me for a while.

As far as I'm concerned it is legit with very high probability. Which, in turn, would imply that if I'm right then Satoshi was alive a few months ago. It would also imply that Craig Wright writing with one space, instead of two, is fraudulent, and that no writing style change has occurred for Satoshi, despite the passing of time since 2010.

Satoshi or not.... he seems like a bit of a cunt doesn't he?

Now-now.  Do not get ahead of yourself.  He said wright was "a bit of a cunt", not a "fucking cunt".  There is a measured difference between 'a bit of a cunt' and a 'fucking cunt'.  I think it is rather unfair to make that leap.
