You can sell “overcomplexity”, “you wouldn’t understand” and “don’t worry about its” for a period of time.
But as soon as someone asks “Why?” – the selling period is over because now you need to explain “why it’s so complex”, “why no one else would understand” and “why, in fact, everyone should understand what is happening.
Selling overcomplexity only works until someone says – “we could do it this way.”
