电影里的“元宇宙”现在是什么样？
What does the movie-style 'metaverse' look like today?
目前多是VR社交、会议或游戏的雏形，头显笨重、内容稀疏，距离《头号玩家》那种沉浸世界还很远。
Today it is mostly VR social, meetings, or games in early form—bulky headsets and sparse content, far from a ready-player-one world.

“数字永生”或“意识上传”现实吗？
Is 'digital immortality' or 'mind uploading' realistic?
眼下能做的只是备份你的资料、模仿你说话，那是一份可复制的画像，不是你本人。两道卡点：一是规模，神经元数以百亿计、连接还多得多，把这套状态完整读出并写到别的载体上，技术差得远；二是身份，就算做出言行一致的副本，它是不是你自己的延续，还是只在旁人眼里像你，复制与连续之间是什么关系谁也说不清。前一道是工程问题，后一道不是。
All we can do now is back up your information and imitate how you talk—that is a copyable portrait, not you. Two barriers stand in the way. The first is scale: the brain's neurons number in the tens of billions and the connections among them far exceed that, so reading such a state completely and writing it onto another substrate is far beyond current technique. The second is identity: even a copy that talks and behaves exactly like you leaves the question of whether it is your own continuation or merely looks like you to other people, and nobody can say what relation copying bears to continuity. The first barrier is an engineering problem; the second is not.

舞台上的“全息投影”是真的全息吗？
Is the 'hologram' on stage a real hologram?
常见的舞台效果多是佩珀尔幻象（用半透玻璃反射影像），真正的全息需要记录光的相位，成本高得多。
Stage 'holograms' are usually Pepper’s ghost (reflecting images on glass); true holography records light phase and is far costlier.

脑机接口真的能“读心”吗？
Can brain-computer interfaces really 'read minds'?
目前的脑机接口只能解码运动意图或简单指令（如帮瘫痪者控制光标），离读取完整思想还非常遥远。
Today’s BCIs only decode movement intent or simple commands (e.g. letting paralyzed users move a cursor); reading full thoughts is far off.

通用人工智能（AGI）已经实现了吗？
Has artificial general intelligence (AGI) been achieved?
还没有。现在的AI多是“窄AI”，擅长特定任务但缺乏真正的理解和常识迁移能力。
Not yet. Today’s AI is mostly 'narrow AI'—good at specific tasks but lacking real understanding and common-sense transfer.

无人机现在已经能完全自己飞了吗？
Can drones already fly fully on their own?
消费级无人机多靠人操控或预设航线，军用有一定自主能力，但目标识别仍受AI局限与伦理约束。
Consumer drones are mostly human-controlled or pre-planned; military ones have some autonomy, but targeting is still limited by AI and ethics.

现在的自动驾驶到底到了哪一级？
What autonomy level has self-driving reached today?
多数量产车是L2（辅助驾驶），少数在试点L3，完全无人（L4/L5）仍局限在固定场景，手还不能离开方向盘。
Most cars are L2 (assisted); a few pilot L3; full autonomy (L4/L5) remains confined to fixed scenarios—hands still on the wheel.

机器人有“意识”和“感情”吗？
Do robots have 'consciousness' or 'feelings'?
目前机器人都只是按程序响应、做统计匹配的工具，没有自我感知，也不会真的难过或开心。
Today’s robots are tools that follow programs and match patterns; they have no self-awareness and don’t truly feel sad or happy.
