When I hear someone says "Agile is Dead" I hear a disappointment, nostalgia that the time has come to say goodbye to something highly valued and meaningful, and also I hear hope there is a way to save Agile.
Do not mix commoditization of ideas (i.e. Kano model) with their death. On the contrary, commoditization means the ideas become ubiquitous. Your business model may be dead, but not the ideas.
On the level of "Agile" buzzword - I don't care. It's probably better that it is dead. Personally, I hope that certifications are dead - all these 2 days trainings for thousands of dollars need to disappear. The quality of those trainings was tragic, their impact - negative. The existence of those trainings clearly reflected the existence of the Agile bubble. A word of mouth and an appealing productivity boost story caused the irrational pressure both on individual level and inside companies to follow the herd. This is how myths and cargo cults are created. Pragmatism and practical daily routines, e.g. XP, design thinking, coaching, is what counts for me. Cutting through the smalltalk and buzzwords, making decisions, getting things done count. Getting the best out of people and empathy count.
On the level of an idea - I do care. Agile is not dead. First, we barely touched agility as the whole thing (take the Integral Agility perspective to understand my point of view). Second, there are ideas building on agility that can take us to the next level. By us I mean not only companies, but in the first place individuals, societies, and the whole humanity.
For those who narrow down the meaning of Agile to organizational effectiveness (aka performance machine), this may sound like claptrap, and I expect them to be among those preachers of 'Agile is Dead'. Don't worry abut these guys - they represent the fixed mindset, and clearly have not appreciated all the lessons learnt from two decades of the Agile era. If you paid them for leading you through Agility journey, I can imagine you find yourself disappointed - leaders abandon you once their business model, i.e. evangelizing without responsibility, collapses. That's the worst thing one can expect from a leader...
Personally, I was processing all the signs of disintegration of the idea of Agile, all the corruption and manipulation that led to the 'Agile is Dead' slogan very carefully. I wrote a few mini-books sharing my perspective on the phenomenon (see Agile 2020s - The Great Retrospective). First of the books were focusing on sharing experiences from the trenches, from the enterprise companies (see The Secret Ingredients of Agile Transformations, or The Landscape of Enterprise Agile Transformations). The latest book, Good Companies, takes a different stand. I have drawn an inspirational future of what is possible if we really care. It took a deep personal journey to discover all the beauty, and all the burden necessary to let the beauty shine, of where we can be if we focus our potential on what is important.
I strongly encourage you to find your own answers, coin your own meaning, and shape your own path, preserving a proper distance from the mainstream mourning of the Agile is Dead' transition.
As a side note, let me brief you with a bit of my personal transformation. If Agile is really dead, that would mean we are able to masacre even the most valuable ideas. I isolate myself from such thinking. I see it differently: we are so trapped in the wrong framing, we do not even realize there is one, and as a result we lost the ability to follow what is important to us. The reductionist frame and the group biases don't let us assess the situation clearly.
A breakthrough is required, and possible as presented in Good Companies, to offer the world the best of who we, humans, are. A journey starts from the current state of how we interact with the world, i.e. Careless Exploitation and leads to state of the Caring Guardianship. It is a state where an independent observer, e.g. one of the species inhabiting the Earth can call our interactions with the world a caring guardianship. I believe this is the best of us that we owe to offer to this world. Whether we can make it will be the ultimate answer of meaning of our existence.
This shift in understanding our role here results in shifts in cardinal aspects of how we understand the meaning of business, the mental model of economy, the relation between societies and the economy, etc. We have not yet started the journey! In my case the triggering event for opening the quest for Good Companies were the observations from many companies that I worked with, and the existing frictions not addressed, not even recognized(!) by digital and agile transformations.
