At age 38 — nearly a decade after maximum hiring age in Silicon Valley — Jack Dorsey would face a daunting challenge were he to accept Twitter’s offer to return to the company he helped found.

Dorsey is currently running Twitter as interim head, and has made no progress yet on the shockingly difficult puzzle of how to monetize billions of brainfarts under 140 characters.

Confirming his interest in the job, Dorsey said this to the tech news site Re/Code, which, strangely, is still in business at this writing:

I’m as committed as ever to Square and its continued success. I’m Square C.E.O. and that won’t change.”

Yeah, right. If Dorsey was definitely rejecting the offer, he would have said: “I am not coming to Twitter. Period.” That is why he is the next CEO of Twitter. And I said that in just 42 characters. But back to the beard …

Dorsey’s beard may be a xenomorph.

Dorsey’s beard is nothing short of xenomorphic, I think. It has appeared in several forms. It appeared first in non-existent form.

There’s also a midrange professorial version:

Now, according to The New York Times and every other biz journal imaginable and with photos, too, Dorsey’s beard has achieved full Portland-cum-Williamsburg status. Witness:

Or with the Amish. Who wants to be the next CEO of Twitter anyway?

Sources on Wall Street and in Silicon Valley say Dorsey stands to become the first owner of a credible hipster beard to become the chief executive of a major American company in memory. Sources are sometimes right, I’ve found.

Hipsters are not hip, by the way.

For the uninitiated, 2015-era hipsters are not “hip,” as the hippies of the 1960s and 1970s called it. Nor are they hipsters in the Jack Kerouac vein.

No. Modern hipsters are dorks, geeks and low-rent careerists whose well-off parents pay their overpriced rents in the slums of Portland, Brooklyn, San Francisco and other cities where they tend to gather in bars and cafés with one-word names like “bar” and “café.”

Dorsey was asked about his beard on CNBC.

“People shouldn’t be measured by what they look like,” Dorsey replied. He is evidently unfamiliar with visual media, not to mention two million years of human evolution.

“Not a fan of the beard,” Dorsey’s mom Marcia tweeted.

But Mashable, which Dorsey likely reads more than his mom’s Twitter feed, loves it:

“Twitter CEO Jack Dorsey sparks shock and awe with lush corporate beard,” said Mashable, which is strangely also still in business as of this writing, oohing, and partially ahhing.

Asked for comment via Twitter direct message, ISIS leader Abu Bakr al-Baghdadi has not gotten back to us.

Neither have the fabled Bubbas with Beards.

And we’re worried about that.

What if, like everyone else, he’s moved on to Instagram? Weirder things obviously have happened.
