He was a good painter and artist we can give him that.

But technology wise he invented nothing. All his ideas were far-fetched and didn't work in reality. He was a big dreamer but incapable of making something practical.

And he contributed nothing to science. I'm unaware of a single scientific theory or idea he contributed. Everything he wrote on science was IFLS tier nonsense.

We need to admit this man was a fraud and stop glorifying him.
