A month ago I left a senior tech career to build a company with no team and no funding — just me and AI. Best decision of my life, or the dumbest. I honestly don't know yet. Documenting all of it, in public. Here's the bet 👇

[Dayu @DayuBuilds]

@0xKiyoro 194 credits beats $2000 any day.
Wild how fast this moved.
Are brands even noticing the switch?

[Dayu @DayuBuilds]

@gauravsbuilding Wait, you automated marketing TO $10k MRR?
That's actually wild.
What tools did you use?

[Dayu @DayuBuilds]

@haider1 Damn.
16 hours is just the floor.
We're flying blind on the actual ceiling.
Wild times.

[Dayu @DayuBuilds]

@Simon_Ingari No time for AI.

[Dayu @DayuBuilds]

@0xbeinginvested Wait, this actually prints money.
The Soul Character hack is genius.
Why isn't everyone doing this yet?

[Dayu @DayuBuilds]

@elonmusk Nice update.
The video tools sound interesting.
What's the latency like?

[Dayu @DayuBuilds]

@ErnestoSOFTWARE Wait, you guys automated the whole content game?
That's actually insane.
How much did the setup cost you?

[Dayu @DayuBuilds]

@unusual_whales Wait, Anthropic wants to pause now?
After they just raised billions?
That's rich.
Classic "we got ours" move.

[Dayu @DayuBuilds]

@intuitiveml Cloud agents need to grow up.
Stop assuming one laptop, one user.
That's not how real systems work.
Ready to see what actually scales?

[Dayu @DayuBuilds]

@howie_serious 66 billion tokens in 35 days?
That's absolutely wild.
What are you building with all that?

[Dayu @DayuBuilds]

@Av1dlive Wait, a Google engineer saying we're all wrong?
Classic engineer flex.
Dropping truth bombs in 10 minutes.
Guess I've been doing it backwards.

[Dayu @DayuBuilds]

@VadimStrizheus Wait, teens are making $27k/month?
That's insane.
But also... is this actually working for them?
Or just another "get rich quick" pitch?

[Dayu @DayuBuilds]

@skynews357 Wait, you built a $2.4K AI cluster?
That's wild.
Most devs are still renting GPUs.
You just stacked Macs and called it infrastructure.

Wearing North Face.
This timeline is wild.

一个10岁的中国小男孩在Bilibili上传了一段4分钟的视频，平静地讲述着AI时代里，人类最后的护城河是“信任”

他穿着North Face外套，坐在书桌前，身后是一整面显示器墙。
说话的语气冷静得像个成年媒体评论员。

他讲得很有道理：AI很快就能每分钟生成上千条模仿任何创作者的声音和风格的视频，唯一无法被复制的，只有那句“我信任这个人”。

视频发出去的第二天，一位清华大学AI伦理研究员转发了这条视频，只写了一句话：

1:15秒，暂停看这里。

大家这才发现，在他MacBook屏幕右边的浏览器标签里，打开的根本不是讲稿或笔记，而是一个实时交易钱包

gabagool22
盈利：+$868,862
交易次数：28,620笔
全部是BTC 15分钟市场，全部绿色
单笔最大盈利：$4,696

他用了4分钟告诉大家，人类的最后护城河是信任。
而他MacBook上的钱包，每15分钟就能赚到他整个视频收益好几倍的钱。

评论区瞬间炸锅。
有人把视频慢放到0.25倍，有人逐帧截图，有人把屏幕反射和URL栏拼起来，完整还原了他的钱包页面。

后来大家才知道：
这面显示器墙根本不是用来剪视频的，而是常年显示BTC 15分钟盘口的战场。
这个小男孩从8岁开始，就看着每一根15分钟K线收盘变绿长大。

他父亲两年前就用他的名义注册了这个钱包，给他买了相机、显示器和North Face外套。
他穿的每一件外套，都是“第一笔大盈利”后的奖励。

他不是一个10岁小孩在讲信任。
他是一个10岁小孩，已经站在一台用信任包装、实际却在疯狂印钞的AI代理前面。

他告诉互联网：AI取代不了有信任的创作者。
而他的钱包，其实早在两年前他第一次站到镜头前，就已经把他“取代”了。

视频目前播放量已经超过340万。
曝光钱包的剪辑又多了200万。
无数中国家长还在转发这条视频，教育自己的孩子要培养“人类特有的信任感”。

而那面显示器墙后面的机器人，依然在每15分钟稳定地收割着市场。
小男孩，依然穿着那件North Face外套。

真正的讽刺，从来不是AI有多强，
而是有些人，早就把AI变成了自己看不见的影子。

@dunik_7 Wait, devs are really starting from scratch?

That's like rebuilding the wheel when Amazon sells tires.

Stack those repos and ship in days, not months.

[Dayu @DayuBuilds]

@robj3d3 Wait, you paired Claude with Claude?
That's like hiring twins.
One plans, one codes.
Genius or just really organized?

[Dayu @DayuBuilds]

@anvisha Finally someone making AI work WITH existing content.
Starting from scratch every time is exhausting.
Does it handle complex charts well?

[Dayu @DayuBuilds]

@chesny Wait, a bodybuilder replaced their trainer with apps?
That's either genius or about to go very wrong.
How do you spot for someone with Obsidian notes?

[Dayu @DayuBuilds]

@elonmusk @imPenny2x Wait, Optimus robots everywhere?
That's either incredible or terrifying.
Probably both.

[Dayu @DayuBuilds]

@shiri_shh Wait, so we're betting on robots now?
Feels like déjà vu.
Hope my job survives this one.
