While I take your point that there is always some uncertainty involved sometimes it is just not that productive to reinforce doubt... otherwise we would never move forward.

Look at climate change... are we 100% certain? Of course not but there is overwhelming evidence that is just prudent to act even for the faint possibility of being wrong.

Same here... logic (how could be creating a living thing to slaughter it and eat it be more effecient than processing and eating the feed itself? That would mean raising an animal with all its (unnecessary) complexity was more efficient than our focused industrial processes...) and evidence (e.g., scientific studies and calculations) very much point to the direction that production of meat alternatives would be much more environmentally friendly (at scale).

I don’t think this is so much about “true believers” but there is simply a lot of evidence pointing in the direction that this is really something that could improve the world in many dimensions.

But you are certainly right that like any other pursuit this should be done dillegiently and with care. If you have specific criticism of some evidence that should be discussed... However, there is no need to be overly sceptic and lay bricks on the road if there is no credible evidence pointing in that direction (In this case baseline skepticism doesn’t seem to hold up against the available evidence at this point). Change will be difficult and reinforcing doubt might delay the development and roll out of viable products at high costs to environment and animals.
