Con The author of the language is an expert con artist
The only reason Vlang has any kind of funding is that it has a lot of dummy repositories that promise a lot of performance to the user (like Gitly, UI, Vinix, Viscord, Vbrowser, DOOM written in V, gg ...), when there is nothing to deliver in the first place. The author of V has a history of overpromising things, has claimed that the language has insane features when it didn't. Having a plain look at their README will give the right idea for someone with programming experience.
Con V 1.0 release was planned for December 2019
Con Highly questionable "Fake it till you make it" marketing
Large parts of what they describe as their "key features" on their website is actually goals, not something they currently deliver. It's also something they never will deliver, because it's impossible to do so. The goals themselves are hyped and unrealistic, and until they have a working prototype delivering the claims (which is largely considered to be impossible by the community), the claims are just lies.
