For web developers and project managers considering moving from a traditional CMS such as WordPress, Drupal or Joomla to a full headless system or hybrid, I highly recommend reading From monoliths to the modern web – The great unbundling.
I’m very happy to see the web evolving into a more platform-agnostic system with benefits wrt speed, security and most importantly multi-purpose content across the digital landscape (web, mobile, chatbots, voice assistants, etc).
In fact my logo (below) represents this thinking in part. One piece of content being distributed to multiple channels. It also represents the fact that an idea is best implemented by a team of specialists who contribute their skills and experience.
