Why has the US constitution been in effect for 200 years?

The US Constitution, adopted in 1787, was the finest document of that era. It was a real constitution, in our modern understanding. Therefore, all her articles are relevant in the United States and now. The only thing that congressmen allow is the introduction of amendments to the articles of the Constitution that reflect modern reality. For example, the development of computer technology or space development.
But the general provisions of the Constitution are relevant for US citizens today, so no one is going to change the constitution.
