Doers can of course criticize, but serious devs won't bash a new and unfinished language, just because the author of the project had the audacity to promise something "so unrealistic".
Healthy people saw V, maybe read about it, saw the great promises, and thought "Ha, that sounds unlikely, but it's not a bad idea, it would be insane if this worked! Shoot for the stars, aim for the moon.".
For others, the promises were outrageous and anything remotely close to them "impossible". I don't get why it got personal for some of us, and it's stupid how involved people were over the years (hey Xe, you're so skilled, why waste your energy) into bashing this random project.
