While I generally agree with this, I think they left off the most important differentiation between technical and recreational diving - becoming a "thinking diver".
I typically describe recreational diving as being able to fall off the boat and ride your computer. And I don't mean that in a demeaning way, but in that we've created a set of rules and training that is robust in nature and designed to keep the vast majority of people in a wide range of environments safe. We've created rule sets that include recreational depth limits, NDL time limits, ppO2 limits, "if-this-happens-do-this" scenarios, etc. They're easy to understand, follow and remember.
When you begin your journey into the tech world, those hard and fast rules and limits are slowly stripped away as your skill level and confidence increases. You may have a trimix card, but does that mean your first post-dive class should be on the Doria? You may have a cave CCR card combined with a cave DPV card, but does that mean it's a good idea to go 30K feet back in a cave just because you're technically allowed to? Heck no, but the only person that's going to stop you is you.
You have to be able to understand the risks of each decision you make and weigh the pros and cons of those. What gear do you need for the dive? How much extra gas do you need? Which gas mixes will be best? There are certainly general guidelines and best practices (and one agency has gone so far as to recommend standard gas mixes) but the ultimate decision is up to you to decide what's best for you and for your dive. You need to understand the "why behind the how" to make a competent decision. That's a "thinking diver".
Oh, and don't get me wrong, there are tons of recreational level thinking divers - and those make great tech students :) - my point is just that, IMHO, your willingness to adjust your dive mentality to becoming a "thinking diver" is the biggest stepping stone to becoming a tech diver and entering into an amazing world of challenging and rewarding dives.
Happy diving!
