Plot twist, Chinese Interstellar civilization from the future travels back in time to help present China overcome both the Thucydides's Trap and the Great Filter.

Meanwhile the Arecibo Message that the US sent out hasn't yet reached not even 0.2% of its intended destination and the whole dish/tower collapsed recently... due to infrastructure decay.

If there is gonna be first contact, it would be the Chinese not the Americans.

Didnt knew about it until now. China and japan are creating the world first quasi-axisymmetric stellarator.

There are several stellerators in the world right now. It is a nuclear fusion reactor concept that in largely solves the problems of the tokamak concept. The quest is on to achieve stellerator optimization. It is possible that a stellerator (HELIAS-5B) could be an alternative to DEMO (sucessor of ITER).

The stellarator isn't a new idea or concept. In fact nearly all fusion reactor designs date from the 1950s or something like that. The tokamak controls the plasma with dynamic magnetic fields. The stellarator supposedly "fixes" the problems with having to do dynamic control in a tokamak with complex design geometry and supposedly less dynamic magnetic field control from what I understand of it. In practice the stellarators typically can't confine plasma as densely as a tokamak so they are mostly for experimental purposes. It doesn't have enough density to become viable in a commercial setting. I am a personal fan of spherical tokamaks to be honest.

A peak of 76 qubit.

Members wrote code to simulate the work of the quantum system on Sunway TaihuLight, China’s most powerful supercomputer and the world’s third fastest, but it couldn’t come close. The researchers calculate the supercomputer would have required more than 2 billion years to do what Jiuzhang did in a little over 3 minutes.

Self-driving robotaxis are taking off in China

The world has been inching toward fully autonomous cars for years. In China, one company just got even closer to making it a reality.
On Thursday, AutoX, an Alibaba (BABA)-backed startup, announced it had rolled out fully driverless robotaxis on public roads in Shenzhen. The company said it had become the first player in China to do so, notching an important industry milestone.
