Later composers must surpass their predecessors in their works. The works of Haydn Mozart are obviously not as great as Beethoven's, because Beethoven grew up by studying the works of these two predecessors. But Haydn Mozart's works are always bigger than those of Samartini and Stamitz. Again, don't use your own subjective preferences to measure others' subjective preferences or objective evaluations. You can say that the shock and enjoyment brought by Beethoven's music cannot be surpassed by any other composer's music, but you can't say that Beethoven's music can't be surpassed. Music and other arts are not like mathematics, physics and other natural subjects, nor are they like philosophy. The latter is always developing, with the increase of methods, tools and cognitive experience. It can also be said that it developed on the shoulders of predecessors, such as Aristotle to Plato, Einstein to Newton. "I don't know how you came to this conclusion, but the development of music creation is really based on previous techniques and concepts." Every technique, style, concept or genre is either influenced by predecessors and developed and innovated on it, or because the previous music form has reached its limit and can no longer be developed, it is completely broken on the surface and rules are re-established. But no matter how each new music form originated, it is closely related to the music of predecessors. "Classicism is classic because of its unsurpassability." I don't quite agree with this either. Everyone likes some composers, so do I, but there is really no need to deify them. In the history of music, nobody can't be surpassed, really.
