Tesla CEO Elon Musk has laid out some bold, if still vague, plans for transforming Twitter into a place of �maximum fun� once he buys the social media platform for $44 billion and takes it private.

But enacting what at the moment are little more than a mix of vague principles and technical details could be considerably more complicated than he suggests.

Here�s what might happen if Musk follows through on his ideas about free speech, fighting spam and opening up the �black box� of artificial intelligence tools that amplify social media trends.

FREE SPEECH TOWN SQUARE

Musk�s feistiest priority � but also the one with the vaguest roadmap � is to make Twitter a �politically neutral� digital town square for the world�s discourse that allows as much free speech as each country�s laws allow.

He�s acknowledged that his plans to reshape Twitter could anger the political left and mostly please the right. He hasn�t specified exactly what he�ll do about former President Donald Trump�s permanently banned account or other right-wing leaders whose tweets have run afoul of the company�s restrictions against hate speech, violent threats or harmful misinformation.

Should Musk go this direction, it could mean bringing back not only Trump, but �many, many others that were removed as a result of QAnon conspiracies, targeted harassment of journalists and activists, and of course all of the accounts that were removed after Jan. 6,� said Joan Donovan, who studies misinformation at Harvard University. �That could potentially be hundreds of thousands of people.�

Musk hasn�t ruled out suspending some accounts, but says such bans should be temporary. His latest criticism has centered around what he described as Twitter�s �incredibly inappropriate� 2020 blocking of a New York Post article on Hunter Biden, which the company has said was a mistake and corrected within 24 hours.

OPEN-SOURCED ALGORITHMS

Musk�s longstanding interest in AI is reflected in one of the most specific proposals he outlined in his merger announcement � the promise of �making the algorithms open source to increase trust.� He�s talking about the systems that rank content to decide what shows up on users� feeds.

Partly driving the distrust, at least for Musk supporters, is lore among U.S. political conservatives about �shadow banning� on social media. This is a supposed invisible feature for reducing the reach of badly behaving users without disabling their accounts. There has been no evidence that Twitter�s platform is biased against conservatives; studies have found the opposite when it comes to conservative media in particular.

Musk has called for posting the underlying computer code powering Twitter�s news feed for public inspection on the coder hangout GitHub. But such �code-level transparency� gives users little insight into how Twitter is working for them without the data the algorithms are processing, said Nick Diakopoulos, a Northwestern University computer scientist.

Diakopoulos said there are good intentions in Musk�s broader goal to help people find out why their tweets get promoted or demoted and whether human moderators or automated systems are making those choices. But that�s no easy task. Too much transparency about how individual tweets are ranked, for instance, can make it easier for �disingenuous people� to game the system and manipulate an algorithm to get maximum exposure for their cause, Diakopoulos said.

�DEFEATING THE SPAM BOTS�

�Spam bots� that mimic real people have been a personal nuisance to Musk, whose popularity on Twitter has inspired countless impersonator accounts that use his image and name � often to promote cryptocurrency scams that look as if they�re coming from the Tesla CEO.

Sure, Twitter users, among them Musk, �don�t want spam,� said David Greene, civil liberties director at the Electronic Frontier Foundation. But who defines what counts as a spam bot?

�Do you mean all bots like, you know, if I follow a Twitter bot that just pulls up historic photos of fruits? I choose to follow that. Is that not allowed to exist?� he said.

There are also plenty of spam-filled Twitter accounts at least partially run by real people that run the gamut from ones that hawk products to those promoting polarizing political content to meddle in other countries� elections.

�AUTHENTICATE ALL HUMANS�

Musk has repeatedly said he wants Twitter to �authenticate all humans,� an ambiguous proposal that could be related to his desire to rid the website of spam accounts.

Ramping up mundane identity checks � such as two-factor authentication or popups that ask which of six photos shows a school bus � could discourage anyone from trying to amass an army of bogus accounts.

Musk might also be considering offering more people a �blue check� � the verification checkmark sported on notable Twitter accounts � like Musk�s � to show they�re who they say they are. Musk has suggested users could buy the checkmarks as part of a premium service.

But some digital rights activists are concerned these measures could lead to a �real-name� policy resembling Facebook�s approach of forcing people to validate their full names and use them in their profiles. That would seem to contradict Musk�s free speech focus by muzzling anonymous whistleblowers or people living under authoritarian regimes where it can be dangerous if a dissident message is attributable to a particular person.

AD-FREE TWITTER?

Musk has floated the idea of an ad-free Twitter, though it wasn�t one of the priorities outlined in the official merger announcement. That may be because cutting off the company�s chief way of making money would be a tall order, even for the world�s richest person.

Advertisements accounted for more than 92% of Twitter�s revenue in the January-March fiscal quarter. The company did last year launch a premium subscription service � known as Twitter Blue � but doesn�t appear to have made much headway in getting people to pay for it.

Musk has made clear he favors a stronger subscription-based model for Twitter that gives more people an ad-free option. That would also fit into his push to relax Twitter�s content restrictions � which brands largely favor because they don�t want their ads surrounded by offensive and hate-filled tweets.

WHAT ELSE?

Musk has tweeted and voiced so many proposals for Twitter that it can be hard to know which ones he takes seriously. He�s joined the popular call for an �edit button� � which Twitter says it�s already working on � that would enable people to fix a tweet shortly after posting it. A less serious proposal from Musk suggested converting Twitter�s downtown San Francisco headquarters to a homeless shelter �since no one shows up anyway� � a comment taken more as a dig on Twitter�s pandemic-era workforce than an altruistic vision for the building.

Musk didn�t return an emailed request to clarify his plans.
