actually it is relevant if you want to run a business for bitcoin, and you need to run a full node , for example you need to know about confirmation time, so you can decide what you can offer to your customers in term of fast transaction
however i can agree that you don't need to know everything about bitcoin, but at least the bases should be known
That's not what the article is about. He does not discuss businesses.
He does not deny it either, and if he is a guy that he is not running any business now, he can in the future maybe, and when that time will come, he will need to know more, about bitcoin, that's what i mean
it is better to have basic knowledges about everything, one never know
also he just saying that, one don't need to know about bitcoin, because the success of it is not tied to its understanding, well no one is saying that you need to understand bitcoin, to help its success, and you need to understand it , only if you work with it, this should be pretty obvious
another example outside the business world is that you need for example to know how much time a confirmation take if you want to send money to your friend, and you don't have enough time to do it and he need that amount asap, so no he is not really correct from my pow
or you need to know how to use fee, if you want transaction fast, and the higher the fee the higher the priority ecc..., so again he is wrong...
