Hello, this is Rookiss.

Due to the invasion of AI, many professions including programmers and accountants, which were once considered safe zones, are disappearing into history.
The current invasion of AI is already chaotic and shocking,
but from a macroscopic perspective, this is merely a scout.

This is because Physical AI, which will arrive in two years, can be seen as the main force of the AI invasion.
Once the invasion of Physical AI, represented by autonomous driving and robots, begins,
'most' of the tasks humans can do, including taxi/transportation/delivery/manufacturing/serving, can be replaced. What does this mean?

It doesn't just refer to 'some' professions like programmers, accountants, and lawyers.
It means that almost all jobs commonly held by people will be under direct invasion.
Even working a short-term part-time job at a convenience store or doing early-morning logistics work at Coupang
could become a luxury no longer permitted to humans.

Far from landing a job at a major corporation or buying a home in Seoul,
a situation may arise where you have to worry about your next meal today.
Looking back at human history, we will feel deeply that food, clothing, and shelter were never things to be taken for granted.
As the dissatisfaction of marginalized people erupts violently into chaos, further destabilizing society,
you might find yourself reminiscing about the past, grateful that you fully enjoyed the most peaceful era in human history, even if only for a short while.

When the era comes where humans command robots and robots do the work,
the meaning of a nation will fade significantly, and it would not be logically strange for an era to arrive where a small number of capitalists
manipulate humanity.
For example, wealthy Mexican cartels
could become more powerful than government forces by commanding robot armies.

No matter how brilliant a person is, they eventually die, and their knowledge is not perfectly transmitted.
However, the knowledge of AI is passed directly to other AI, meaning it can never regress.
Once you fall behind in the AI war, the gap will only widen, and a reversal will inevitably become increasingly difficult.
It is likely no coincidence that all big tech companies at this point are staking their lives on the AI war, even if it means manipulating their books.

The future I envision is also not bright.
However, rather than such a future arriving suddenly one day, there will certainly be a period of transition.
And this transition period might be the last opportunity to determine my future status.

Being swept away by the first wave of LLMs because you weren't prepared
is a flow of the times that truly no one could help.
But if you fail to prepare at all for the clearly predictable second wave of Physical AI,
then you must bear some level of responsibility yourself.

So, to survive in the future society amidst such chaos, what specifically should we prepare for?
I am holding a seminar to predict the changes coming in the future and organize what to prepare and study,
covering both short-term & long-term plans.

Today, after a long hiatus, [Unreal Agent from Scratch]—the result of Liu's research for a full 6 months—has been released as Early Access.
Please take a look at the amazing results you will complete in this course.

This course is not just a one-time follow-along using an MCP someone else made.
It is a course where you master fundamental technologies by implementing the Agent - Tool - MCP stages from scratch.
To summarize in one sentence, you can think of it as building an Agent like Claude Code from the ground up.

In the not-too-distant future, an era may come where games are developed with just a single "click" request.
Therefore, we have entered an era where we must continuously observe the advancement of AI,
and everyone must possess AI utilization skills as a basic literacy.

Although this course is themed around [Unreal Engine Agent],
knowledge of [Unreal Engine] is not required because it is not a course specifically specialized only for gaming.

Rather, since it is a course that demonstrates real-world examples of creating and utilizing Agents
using [Unreal Engine]—which is much more difficult than general Agents—as the subject,
if you understand this content overall, you will gain the ability to utilize
Agents in any field.

Please refer to the course introduction for more details.

Thank you.
