这款能一键把人变老好几十岁的应用，正是现如今风靡全球的FaceApp。
FaceApp first went viral in 2017, but with many updates since then, the technology has become even more realistic, causing it to go viral once again. The free version offers a limited choice of filters, but don't worry, the one that ages you is available for free. You also have options to change your face, including changing your mouth to a smile, change the color of your hair, and swap genders.
FaceApp was developed by a small team out of Saint-Petersburg, Russia.
FaceApp由俄罗斯圣彼得堡的一个小型团队研发。
\"We developed a new technology that uses neural networks to modify a face on any photo while keeping it photorealistic,\" founder and CEO Yaroslav Goncharov told TechCrunch.
其创始人兼CEO Yaroslav Goncharov对TechCrunch表示，团队研发出了一项新技术，可以利用类神经网络来改变任何照片上的人脸，同时还能保持照片逼真。
\"Our main differentiator is photorealism,\" he said. \"After applying a filter, it is still your photo. Other apps intentionally change a picture in a way it is entertaining, but not a real photo anymore.\"
Goncharov说，逼真是我们最大的不同，在使用一款滤镜后，照片还是你的照片。而其他应用会用好玩的方式故意变换照片，但照片的真实感就没有了。
photorealism：照相写实主义（如照片一般精确细致地表现主题）
然而这样一款变脸神器也引发了人们的担忧，尤其是其中的安全问题。

Digitas strategist James Whatley shared the fine print on Twitter, calling the terms of service agreement a “Doozy.”
数字营销公司Digitas战略专家詹姆斯·沃特利在推特上分享了部分协议内容，称其中的一些条款“不寻常”。
“You grant FaceApp a perpetual, irrevocable, nonexclusive royalty-free, worldwide, fully-paid, transferable sublicensable license to use, reproduce, modify, adapt, publish, translate, create derivative works from, distribute, publicly perform and display your User Content and any name, username or likeness provided in connection with your User Content in all media formats and channels now known or later developed, without compensation to you,” the agreement states, in part.
协议中指出：“您授予FaceApp永久、不可撤销、非排他性免版税、在全球范围内、全额支付、可转让可再授权的许可，以使用、复制、修改、改编、发布、翻译、创建衍生作品，分发，公开处理和显示您的‘用户内容’，以及任何与‘用户内容’相关的名称、用户名或照片，这些内容以现在已知或此后开发的媒体格式和渠道提供，无需对您进行补偿。”
Privacy expert David Vaile, the chair of Australian Privacy Foundation, told the Australian Broadcasting Corporation that “they ask for way more rights than they need” and “it is impossible to tell” what is done with the uploaded content.
而澳大利亚隐私基金会主席、隐私专家大卫·韦尔则对澳大利亚广播公司表示，他们要求的权限远远超过了他们所需要的，而且很难说会对上传的内容做些什么。
不过，该公司创始人Yaroslav Goncharov则声明，并没有“向任何第三方销售或分享用户数据”（the company does not“sell or share any user data with any third parties”） 。
“We might store an uploaded photo in the cloud. The main reason for that is performance and traffic: we want to make sure that the user doesn’t upload the photo repeatedly for every edit operation,” he says. “Most images are deleted from our servers within 48 hours from the upload date.”
除了对应用自身安全问题的担忧，外国网友们对这场“变老挑战”表现出了深深的焦虑……

Comedian Mark Mehigan had a rather heartbreaking encounter with the coldness of life as well as the chill of death. He tweeted: \"Just posted a photo of my late grandad on Instagram as it's the anniversary of his death and people think it's a Faceapp so keep commenting 'lol' and 'old c***' underneath it.\"
也有网友们感到了惊慌和焦虑：
“有如下经历的人举手：下载faceapp想把自己变老，以为又萌又好玩，然而效果太真实了，于是引发一波生存危机，甚至开始思考自己的死亡，细思极恐！！”
“FaceApp很酷地提醒了大家人脸识别已经走了多远！而且每一天我们都离死亡更近了一步！这可真好玩！”
“Faceapp让我为生死焦虑。”
“我儿子的朋友们在家过夜。他们想要拍我的照片放在faceapp上，我的反应让他们不大乐意了。我说‘不！我会随着时间自然老去并走到人生尽头，我更想那时候再知道自己的样子。谢谢！’”
面对“变老挑战”，你们会感到惊慌难过吗？大家怎么看？
