I am not sure that I agree with this narrative. What i think is that a new developer should learn the bare basics of Sol and then create any kind of a coin.

Then, they should try and find any kind of the team and try and work there. In a couple of money, they'll get the basics in place.

Just learning something won't make any good.

Also, I don't agree that there is a need to know another contract-oriented language, and ofc you don't need to learn Viper.

I am a contentwriter, and I am gradually migrating into writing about crypto and learning solidity. I will seriously freak out if anybody will ever ask me about Vyper. It might be used in some projects, but it's much better to do a couple of coins for yourself and test it out as opposed to learning Vyper or anything like that.
