You have returned to ad hominem attacks and misrepresentations of what I wrote.
I really can’t help it if you present yourself as an idiot.
Life size animatronic models have been built of some of the larger dinos, particularly the ones we have complete skeletons of. If you have something to say about structural impossibilities, I suggest you build a model and test your engineering hypotheses.
My own experience leads me to think that living creatures are stronger and more agile than animatronics. In any case, it would be fairly easy to test your hypothesis about maximum neck length.

Some of the smaller ones are obviously costumes worn by people, but the principle remains the same: if you want to demonstrate that a structure is impossible, build one.
