社交媒體不再屬于你,不再屬于你的朋友,不再屬于仍留在家鄉(xiāng)的中學(xué)同學(xué),也不再屬于你設(shè)置靜音但沒法取關(guān)的古怪表弟,因?yàn)楫吘故羌胰?。如今的社交媒體已徹底成為意見領(lǐng)袖和靠制作內(nèi)容為生的創(chuàng)作者的地盤。

社交媒體上已無普通人的立足之地。

“公開的社交媒體上,普通人發(fā)布的內(nèi)容少了很多。”周一,Creator Ventures的聯(lián)合創(chuàng)始人兼管理合伙人薩沙·卡萊斯基在阿布扎比舉辦的《財(cái)富》全球論壇上表示?!耙虼?,你的信息流里不再是高中朋友或七年前畢業(yè)舞會舞伴的動(dòng)態(tài)?,F(xiàn)在只能看到專業(yè)制作的娛樂內(nèi)容?!?/p>

創(chuàng)作者經(jīng)濟(jì)規(guī)模非常龐大,已經(jīng)將社交媒體網(wǎng)絡(luò)從愉快分享之處變成蓬勃發(fā)展的內(nèi)容業(yè)務(wù)全球分發(fā)平臺。高盛(Goldman Sachs)一份報(bào)告顯示,預(yù)計(jì)到2027年創(chuàng)作者經(jīng)濟(jì)將成為4800億美元的產(chǎn)業(yè),幾乎是目前2500億美元的兩倍。

創(chuàng)作者經(jīng)濟(jì)不斷發(fā)展的同時(shí)也在改變社交媒體平臺。創(chuàng)作者常常受科技巨頭的算法支配。算法變化時(shí),社交媒體的性質(zhì)也會發(fā)生變化,迫使在平臺上謀生的人們跟著調(diào)整。正如一些科技高管所說,過分追求參與的算法有時(shí)會對用戶體驗(yàn)造成損害。

社交媒體服務(wù)正變成“分發(fā)平臺,而不是粉絲平臺”,卡萊斯基表示,“各種原創(chuàng)平臺,不管是Twitter(現(xiàn)在改名為X)、Instagram,甚至當(dāng)年的Facebook通用規(guī)則都是,用戶既關(guān)注朋友也關(guān)注某些創(chuàng)作者,然后在訂閱列表中看關(guān)注者發(fā)布的內(nèi)容。信息流里有朋友發(fā)的內(nèi)容,也有創(chuàng)作者發(fā)的內(nèi)容?,F(xiàn)在已經(jīng)完全不同。未來五年將徹底變成完全看不到朋友動(dòng)態(tài)的情況?!?/p>

卡萊斯基說,BeReal和Dispo等新出現(xiàn)的社交媒體公司希望將社交媒體扭轉(zhuǎn)回當(dāng)初主要在朋友之間交流的樣子。但成功案例很少。除了BeReal和Dispo,卡萊斯基還提到了另一款社交應(yīng)用Poparazzi,在蘋果應(yīng)用商店排行榜上躋身前列一兩年后于今年5月關(guān)閉。盡管有人在努力復(fù)興老派社交媒體,然而用戶扎堆的應(yīng)用都出自Meta、TikTok和Alphabet等當(dāng)前科技巨頭,還有Snap和Twitter。

Creator Ventures聯(lián)合創(chuàng)始人卡斯帕·李表示,在當(dāng)前形勢下,TikTok和Alphabet旗下模仿TikTok的YouTube Shorts有望成功?!癤機(jī)會小一點(diǎn),因?yàn)閄平臺上的內(nèi)容跟品牌關(guān)聯(lián)比較弱,比較難發(fā)展,如果品牌愿意付錢給創(chuàng)作者,讓他們繼續(xù)在當(dāng)前平臺上創(chuàng)作內(nèi)容,創(chuàng)作者就能活得很好?!崩钫f。

內(nèi)容創(chuàng)作者和贊助內(nèi)容的廣告商之所以發(fā)現(xiàn)TikTok和YouTube Shorts很有吸引力,主要因?yàn)辇嫶蟮挠脩艋鶖?shù)。根據(jù)Alphabet的數(shù)據(jù),YouTube Shorts每月登錄用戶達(dá)20億。截至今年3月,TikTok在美國的月活躍用戶約1.5億。而且一般來說,品牌投放的廣告和贊助內(nèi)容旁邊不會出現(xiàn)存在爭議或冒犯性的內(nèi)容,這是一直困擾X的問題。

僅在過去一周,X就流失了一些大廣告商,原因是X的所有者埃隆·馬斯克似乎支持了一個(gè)反猶太人的帖子。該事件之后,蘋果、IBM和旗下?lián)碛蠳BC環(huán)球的康卡斯特(Comcast)等大公司都表示將暫停在該平臺投放廣告,X現(xiàn)任首席執(zhí)行官琳達(dá)·雅卡里諾還曾在NBC環(huán)球負(fù)責(zé)全球廣告銷售。在馬斯克的領(lǐng)導(dǎo)下,8月X曾嘗試推出全新的廣告收入分享計(jì)劃,對有能力制作熱門內(nèi)容的創(chuàng)作者提高激勵(lì)金額。不過受馬斯克的反猶太主義拖累,相關(guān)舉措進(jìn)展很難衡量。

沒有什么比“人工智能生成的人物更不真實(shí)”

意見領(lǐng)袖不僅要跟隨社交媒體平臺的戰(zhàn)略調(diào)整,還要應(yīng)對世界上最受關(guān)注的新技術(shù)崛起:人工智能。李和卡萊斯基都認(rèn)為,人工智能在幫助創(chuàng)作者方面將發(fā)揮著關(guān)鍵作用,并不會完全取代。隨著人工智能發(fā)展,將出現(xiàn)新工具幫助創(chuàng)作者制作更多內(nèi)容,如今已經(jīng)成為不少初創(chuàng)公司、老公司和投資者的搖錢樹。舉例來說,PitchBook的數(shù)據(jù)顯示,卡萊斯基的公司Creator Ventures就已投資了估值10億美元的初創(chuàng)公司ElevenLabs,該公司利用人工智能模仿人類的聲音。

還在為YouTube頻道制作內(nèi)容的李說,最近由于一個(gè)短劇中找不到其他人當(dāng)配角,就嘗試用了ElevenLabs完成。

“通常情況下,如果視頻里需要另一個(gè)角色,我會強(qiáng)迫媽媽或者未婚妻幫忙?!崩钫f?!暗@次她們都沒空。所以我只好用了ElevenLabs,這樣內(nèi)容里會出現(xiàn)另一個(gè)聲音,沒人知道這是人工智能生成的聲音?!?/p>

李補(bǔ)充說,這只是一個(gè)視頻里的“隨機(jī)角色”,所以“沒什么大不了?!钡?,如果使用人工智能生成的聲音變得很普及,創(chuàng)作者和平臺就要明確提示觀眾哪里是人工智能。

最近幾個(gè)月,人工智能已經(jīng)滲透到了創(chuàng)作者經(jīng)濟(jì)的方方面面。類似Meta之類最大的社交媒體公司甚至已經(jīng)開始試驗(yàn)純?nèi)斯ぶ悄芤庖婎I(lǐng)袖。這一嘗試引發(fā)一些父母、藝術(shù)家,還有發(fā)現(xiàn)自己作品頻繁遭模仿的創(chuàng)作者的質(zhì)疑。相關(guān)創(chuàng)新代表了人工智能新的應(yīng)用方式,對于不必向?qū)嶋H創(chuàng)作者付費(fèi)的平臺來說,可能是削減成本的大好機(jī)會。但卡萊斯基認(rèn)為真人意見領(lǐng)袖不太可能被取代。

“人們之所以關(guān)注社交媒體創(chuàng)作者,之所以愿意花工夫,部分原因是他們是真實(shí)的。”卡萊斯基說?!笆澜缟蠜]什么比人工智能生成的人物更不真實(shí)。因此,人工智能在很多方面都比不上人類。”

不過卡萊斯基也委婉地說,人工智能生成角色可能是不錯(cuò)的投資。“如果市場規(guī)模巨大,對我們來說是好消息,因?yàn)樵趧?chuàng)作者經(jīng)濟(jì)中我們是技術(shù)投資者?!彼f?!叭绻斯ぶ悄茏罱K超過人類那就更棒了。但我認(rèn)為不會出現(xiàn)?!保ㄘ?cái)富中文網(wǎng))

Social media no longer belongs to you, your friends, that random guy from middle school who still lives in your hometown, or your weird cousin you muted but can’t unfollow, because, well, they’re still family. It’s now entirely the domain of influencers and creators who make content for a living.

There’s just no more room for regular people on social media.

“People are posting a lot less on public social media,” Sasha Kaletsky, cofounder and managing partner at Creator Ventures, said Monday at the Fortune Global Forum in Abu Dhabi. “And so your feed is no longer made up of your high school friends or your prom date from seven years ago. Now you’re just seeing people who are professionally entertaining you.”

The creator economy is such a big business that it has turned social media networks from a place of convivial camaraderie to a global distribution platform for the booming content business. By 2027 the creator economy is forecasted to be a $480 billion industry, almost double the sector’s current value of $250 billion, according to a report from Goldman Sachs.

The nature of the evolving creator economy is changing social media platforms as well. Creators have often been at the mercy of the algorithms of Big Tech. When those algorithms change, so does the nature of social media, forcing those who make a living on those platforms to adjust accordingly. Those algorithms, which are meant to drive engagement above all else, can sometimes harm user experiences, as some tech executives have argued.

Social media services are becoming “distribution platforms rather than follower platforms,” Kaletsky says. “All these original platforms, whether it’s Twitter [now known as X], Instagram, even Facebook back in the day, were things where you would follow certain creators alongside your own friends, and watch their content in your feeds. It’d be a friend, and it’d be a creator next to each other. That’s changing completely. In five years, that will have totally changed to the extent that you don’t bother with friends anymore.”

There have been upstart social media companies—BeReal and Dispo, for example—that have tried to revert to the original friend-oriented version of social media, Kaletsky says. But none of them caught on. Poparazzi, another app that Kaletsky cited alongside BeReal and Dispo, shut down in May, just two years after topping the charts of Apple’s App Store. Despite the efforts to revive the old school of social media, today’s engagement-heavy version is dominated by incumbent tech giants like Meta, TikTok, and Alphabet, along with Snap and Twitter.

In the current landscape TikTok and YouTube Shorts, Alphabet’s TikTok copycat, will succeed, according to Caspar Lee, a cofounder at Creator Ventures and an influencer in his own right. “X slightly less so, because it’s hard with the fact that the content that is coming up on there doesn’t work for brands, and creators thrive when brands are happy to pay them to create content on platforms they’re creating content on,” Lee says.

Content creators, and the advertisers that sponsor their content, find TikTok and YouTube Shorts appealing because of their big audiences. YouTube Shorts has 2 billion logged-in monthly users, according to Alphabet, and as of March, TikTok had roughly 150 million monthly active users in the U.S. They also, generally speaking, can reassure brands that their ads and sponsored content won’t appear next to controversial or offensive content, something that X has struggled with.

In the past week alone X suffered an exodus of major advertisers after its owner, Elon Musk, appeared to endorse an anti-Semitic post. Since then, blue-chip companies like Apple, IBM, and Comcast—which owns NBCUniversal where current X CEO Linda Yaccarino previously led global ad sales—all said they would pause advertising on the platform. Under Musk, X has tried to court creators by implementing a new ad revenue sharing program in August meant to increase payments to creators who have popular content. Although the progress of those initiatives has been difficult to gauge, mostly because it’s been overshadowed by Musk’s brushes with anti-Semitism.

There is nothing ‘less authentic than an AI-generated character’

As influencers navigate the shifting strategies of social media platforms, they also have to contend with the rise of the world’s most talked-about new technology: AI. Both Lee and Kaletsky believe it will play a pivotal role in helping creators without replacing them entirely. AI will lead to new tools to help creators produce more content—already a cash cow for startups, established players, and investors alike. Kaletsky’s firm, Creator Ventures, has, for example, invested in ElevenLabs, a startup valued at $1 billion, according to PitchBook, that uses AI to replicate human voices.

Lee, who still makes content for his YouTube channel, said he just recently used ElevenLabs for one of his own videos when he couldn’t find someone to play a supporting role in a skit.

“Usually if I need another character in a video, I’d have to force my mom to be in it or my fiancée,” Lee says. “But this time they weren’t available. So I just used ElevenLabs, and I was able to get a voice to be in the content, and no one knew it was an AI-generated voice.”

Lee adds that this was just a “random character” in one of his videos, so it “didn’t matter so much.” But if using AI-generated voices became the norm, creators and platforms would have to find a way to let viewers know when it was being used.

AI has creeped into all facets of the creator economy in recent months. Some of the biggest social media companies like Meta have even begun experimenting with entirely AI-generated influencers. The effort has raised some eyebrows, from concerned parents and artists and creators who have seen a rise in digital imitations of their work. Those sorts of innovations represent a novel application of AI, and probably an appetizing cost-cutting opportunity for platforms that wouldn’t have to pay a real creator. But Kaletsky thinks they’re unlikely to replace actual influencers.

“The reason people follow social media creators, the reason they bother, is partly because of the authenticity,” Kaletsky says. “There’s nothing in the world that’s less authentic than an AI-generated character. So it sort of defeats the point in many ways.”

But Kaletsky hedged by saying AI-generated characters could make for a good investment. “It’d be very nice for us if that’s going to be huge, because we’re technology investors in the creator economy,” he says. “It’d be wonderful if that takes over. But I don’t think it’s going to.”
