The fact that the post mentions hiring (cost) isn't my hesitation. It's that bringing cost into a conversation about the technical merits of a given technology can be a heavy-handed way of shutting down the conversation. In some cases, technical merits very much do justify the cost, but that can only happen by creating the space to find out.

Said differently: I believe it's often worthwhile to discuss the deeper technical merits of options without hastily jumping to a cost discussion.
