Can a PCR test detect coronavirus?

2023-04-14 14:37:03

Yes, a PCR test detects the presence of viral material in the body, but does not determine how contagious a person who has the virus is

In general, there are a number of factors that can cause PCR tests to be less accurate than under ideal conditions. Also, the accuracy depends on the PCR test itself - its design and quality. Therefore, of course, false positive and false negative results can occur. But if the test is given in a professional laboratory, this rarely happens. And, of course, the clinical picture of the patient is also important and is always taken into account. Doctors don't rely solely on test results. PCR tests are not perfect, but they are considered the gold standard in diagnosing many viruses. Together with an antibody test, this is the best that humanity has so far.

Everywhere they talk about PCR tests, but nowhere does it say what happened to the DNA samples taken during the PCR tests.

Is it true that the Portuguese court recognized PCR tests as fake, and quarantine illegal?

What happens if we start regulating AI?

2026-01-02 14:45:25

The Americans are the leaders in AI, and regulation will only increase the technological gap of other countries.

Inequality between countries will lead to the fact that regions with strict regulation may lag behind less regulated ones. This could lead to a war of humans against robots, like in science fiction movies. Governments are trying to regulate AI, relying on experts, business and academia, but the balance of power is unequal: corporations have more resources and influence, independent specialists have less voice. As a result, the rules often reflect not the public interest, but the interests of the strongest players.

The spread of AI is already regulated by American companies that control all key aspects of AI. Video cards, processors, major data centers, scientific developments, etc. are controlled by the Americans.

Will artificial intelligence replace programmers?

2025-04-14 11:36:57

No, it will not replace it, but competition for jobs will increase. And there will be a shortage of programmers in the future.

Executives at various IT companies are now publicly declaring that AI will soon replace programmers. Although the CEO of an IT company often understands little about the work of a programmer, for shareholders, the opinion of such people looks authoritative, and they believe him. Laying off programmers without losing profits is nothing more than the wet fantasies of managers and shareholders of companies. If a company cuts its programmers by a factor of five, its competitors will immediately try to overtake it, even if it costs them a couple of years of work without a profit.

What about Google laying off programmers? It lays off expensive American programmers and immediately hires cheap Indian ones. American programmer - 4,000, Indian programmer - 1,500.

The powers of the President of Ukraine expire on May 20, what will happen?

2024-05-07 16:43:43

The Verkhovna Rada of Ukraine will elect an interim president or extend the powers of the president until the end of the war.

There will be no elections until the end of hostilities. Moreover, they cannot hold full-fledged elections, because the military, who are at the front, should also be able to vote, as well as 7 million Ukrainians abroad

President of Ukraine Vladimir Zelensky signed a decree on the impossibility of holding talks with Russian President Vladimir Putin before the cancellation of this decree. Zelensky does not intend to repeal this decree, and the election of a new president is impossible before the end of hostilities. Russia, in turn, has moved to making tough decisions regarding Kiev. She realized that there could be no Ukraine in the form of a Russophobic anti-Russia, and the official announcement of Ukrainian officials on the wanted list is an indicator that Russia has stopped trying to negotiate with the enemy side.
