Question around ease of creating smart contracts on NEO, as opposed to Ethereum

Hi Guys,

Saw a post on a website today stating that it's extremely difficult (basically impossible) to write smart contracts in standard programming languages (JavaScript, C++, C# etc.), and that is why Ethereum uses Solidity (sp?) because it's highly simplified and makes it possible to write smart contracts.

Is this true? I can't see it being true, as it's a major flaw in practically the whole NEO model, but is someone more knowledgeable than myself able to explain what maybe they meant?

Thanks in advance
