Faking in demo video is now an essential evil to get virality . Because social media is about virality . All commenting on the video and this thread are now curious to try Devin, to prove it works or to prove it doesnt .
So now if it works faking helped it get virality , more users , more demand for product .
If it doesnt work good enough still it will be good enough for some of the users who discovered it because of the virality .
Only worst case is it is too hopelessly bad or doesnt work at all or tried to get to the moon and got nowhere . Hope the founders are smart enough to not be this bad
