What causes cancer?

2023-12-14 13:46:11

Cancer arises from a large number of accumulations of mutations in cells. In the presence of mutations in genes that control cell growth, cells can continue to divide and form a tumor.

Normal cells become malignant due to mutations. Changes in genes accumulate gradually, it is a long, complex process. When such changes occur in cells, the body tries to get rid of them. Various mechanisms of cell death are activated, and antitumor immunity is activated. But malignant cells skillfully cope with these obstacles by developing masking mechanisms to avoid immune aggression.

A cancerous tumor does not have a complete form and, in addition to the main body, has many thin processes-metastases that cannot be removed along with the main tumor, and the remaining metastases in the body grow back into a malignant tumor and so on until the person dies.

Malignant cells – how do they differ from normal ones?

Why have all the big companies turned to AI now?

This is a strategic and economic trend. Investing in AI is about saving, growth, innovation, and HR strategy at the same time.

By 2045, the global IT market will become clearly concentrated, with several leading players and a high market share. It should be noted that the market may shrink by about 1.5‑3 times in terms of the number of active professionals, but at the same time the quality, complexity and value of these specialists will increase.

It is safe from the point of view of control not to go into AI, but it is almost guaranteed to lead to lagging behind and loss of market share, especially if competitors actively use AI. In a highly competitive world where speed and scale are important, not using AI can be worse than the risk of failures in its implementation.

What awaits Europe in 2025?

2025-01-22 02:56:02

Quarrel with the United States, trade war, difficult economic situation, shortage of energy resources, rising unemployment

Some European countries have large trade surpluses with the United States. Trump is demanding that Europe buy more American goods to smooth out this surplus. An increase in the number of American goods on the European market means the automatic displacement of European manufacturers, the potential bankruptcy of medium and small enterprises, their consolidation and monopolization by American multinational companies and, ultimately, the subordination of the European economy to the United States, which Europe, of course, will not agree to. Gas transit through Ukraine has been stopped, and Europe has lost almost its last gas source through the pipeline. The EU is purchasing Russian LNG at a record pace, and the United States is pushing its allies to ban it. The EU should increase purchases of American hydrocarbons, if the EU ignores this, it will receive protective duties on its products supplied to America. It will end with a shortage of fuel and another price increase. Trump also intends to increase the military spending of NATO countries to 5% of their GDP.

Trump is putting forward exorbitant demands on Europe, which will significantly affect military-economic cooperation between the United States and Europe in the direction of deterioration and cessation. Because of this, some countries will leave the EU in the future. Europe, in which every country will fight for its own well-being, will return.

Why is OpenAI buying up all the components?

In practice, large-scale purchases of GPUs and memory, buying up the best AI labs, and poaching top researchers are a powerful tool for eliminating competitors, especially small and medium-sized players.

In part, this destruction of competitors is not direct, but through economic and technological strangulation. OpenAI and Microsoft do not have to want to harm others - it is enough for them to maximize their progress, and the market itself will exclude the weak. The goal is that the future of AI is determined by 2-3 corporations, not a community of scientists, startups and public organizations.

The main threat is not from AI as a technology, but from the one who owns it.
