While the "upload" mode is powerful, does it also lead to issues such as information overload, widespread misinformation, and cyber violence?

Okay, that's a really great question, and it's incredibly pertinent to our daily lives right now. Let me share my thoughts.

Yes, absolutely, it's a razor-sharp double-edged sword.

The "upload" model, or what we often call User-Generated Content (UGC), is essentially like handing everyone an ordinary person the kind of high-powered "megaphone" that used to be reserved for a select few professionals (like journalists, writers, directors).

This is, of course, a revolutionary advancement. In the past, we could only "listen"; now, we can also "speak." A child from a remote mountain village can share his life through short videos; an ordinary technician can write blog posts to share his problem-solving expertise. This is a classic manifestation of "The World is Flat" – it gives countless ordinary people a voice and a platform to showcase themselves.

However, now that everyone has a "megaphone," problems inevitably arise, and they align perfectly with the points you mentioned.

1. Information Overload: From "No Choice" to "No Idea How to Choose"

An Analogy: Before, when you wanted water, there was only one well, so you had to get water there. Now, suddenly thousands of faucets appear in front of you – some dispensing purified water, some tap water, some carbonated drinks, and even some spewing dirty water. Before you even get to drink, just choosing which faucet to use is headache-inducing.
The Reality: Every day we open our phones – Weibo, Douyin, Bilibili, official accounts... a deluge of information hits us like a waterfall. Our attention and time are finite. The sheer volume of mixed-quality content leaves us feeling exhausted and makes it incredibly hard to find truly valuable and useful information. Ultimately, we might just wind up consuming our time endlessly refreshing feeds.

2. Proliferation of Misinformation: The Cost of Spreading Lies is Too Low

An Analogy: Previously, the "megaphone" was held by newspapers and TV stations. Before broadcasting, they had to go through editing and vetting. While not guaranteeing 100% accuracy, there was at least a "gatekeeping" process. Now, anyone who grabs the "megaphone" can shout directly, and making a mistake costs them almost nothing and has little consequence.
The Reality: Driven by the desire for traffic, shock value, or even just for fun, creating and spreading misinformation becomes incredibly easy. Stories spun from a "single picture with fabricated details" are played out daily. Often, sensational fake news spreads much faster and wider than mundane truths. Adding fuel to the fire, platform recommendation algorithms tend to promote content that provokes strong emotions.

3. Online Harassment: The "Blameless" Attack from Behind the Screen

An Analogy: When arguing face-to-face, you factor in the other person's reaction and the onlookers. The internet gives everyone a mask, making you feel like you can wield that "megaphone" irresponsibly to scream or throw stones at someone, because they can't see you, and you can't feel the real pain you cause them.
The Reality: The "upload" model isn't just for uploading creations; it also includes uploading comments and opinions. Anonymity drastically lowers the psychological barrier for harmful behavior. The slightest disagreement can lead to personal attacks, doxxing (revealing private information), and slander. Groups of people can easily gang up on an individual, creating a "tyranny of the majority." This inflicts real and lasting psychological damage.

To Summarize

So, the power of the "upload" model lies in granting the masses an equal voice and shattering information monopolies. But its drawbacks stem precisely from this – the barriers are too low, vetting is lacking, and accountability is absent.

It’s like opening Pandora's box. Countless opportunities and creativity were unleashed, but so too were chaos, lies, and malice.

What we can do now isn't to close the box (because it's impossible anyway), but to learn how to survive in this world filled with countless voices:

Boost Your Own "Information Immunity": Learn to discern information – don't believe it blindly or follow it unquestioningly; seek verification from multiple sources.
Be a Responsible "Voice": Value the "megaphone" in your hands. Exercise more reason and kindness when expressing opinions or posting comments.
Advocate for Healthier Platform Rules: Hope that platforms will shoulder more responsibility, refine their algorithms, and more effectively combat misinformation and online harassment.

This is likely an unavoidable challenge that everyone in our era must confront.
