I still wouldn't like that he just recycles ideas from someone else and using it for other plots. Even Vegapunk made it recently as it was said in EL/Alabasta. And it was shown to be something of the sort which was a unique tech he created. We already got some BS with Judge and his weird tech and now I can see all science BS to be added here and there. I was hoping it to be a proper unique plot which will revolve around Vegapunk, science is already just his random thoughts mixing without any thought to science itself. But now with even this...first smiles, then this items eating smiles...too much for me to take any hype for Vegapunk now
But the whole point is likely to show that every big ideas came from vegapunk and other managed only to deepen some of his ideas, and often their results are imperfect and only vegapunk can truely succeed
