Software architecture is in crisis, and the way to fix it is a hefty dose of anarchy.

I think he saved us; bringing us back to the path of value-delivery and independent services, but now with added independent teams.

*Shudder*
And consequently many, many #microservices adoptions failed; with #microservices themselves getting an undeserved bad name in the process.
What we need is a workable way to approach them, and in the process realise the associated benefits of both team autonomy and improvements in system architecture.
I’ll describe what it is and you could do it. Hopefully you’ll see how it offers the best (only?) way out of this mess.
Straight away that means how we are used to doing architecture, via all-powerful architects taking all the decisions, is going to have to stop.
\u201cYou may think in describing anarchism as a theory of organisation I am propounding a deliberate paradox: \u2018anarchy\u2019 you may consider to be, by definition, the _opposite_ of organisation. In fact, however, \u2018anarchy\u2019 means the absence of government, the absence of _authority_. ..."

(As @Grady_Booch has said “architecture represents the set of significant design decisions that shape the form and the function of a system, where significant is measured by cost of change.”)
So the first test is can an #AnarchisticArchitecture deliver on this?
The answer is "Yes".
