Jesus, 10 people on a team? What are you doing that you need 10 people to work on it? I manage like 8 services by myself.
These days I kinda wince at "I run 8 services myself."
If it takes 1 person to run 1 microservice, we are all doomed.
I also feel that ceteris paribus, the meetings got longer, project management tools now consume a lot of input from programmers, and I need to communicate with a lot more people to get something done.
Which seems to end up meaning productivity has gone down when measured by "things end users of websites can do", even though modern FE devs end up creating much more code and html and css than "the old days". (Admittedly, if you include privacy invasion, user tracking, and various other requirements of surveillance capitalism, dev productivity has probably skyrocketed...)
Complex? We still call a function with a return value on a stackmachine.
Sorry for the negativity.
And yet, most homepages today can't be viewed without javascript. You are correct, for the end user the complexity has absolutely not resulted in better homepages but worse.
Higher levels of abstraction makes it easier to get something up and running fast, but at some point you need to be able to look under the hood and understand what's going on, and many programmers today can't do that.
That being said I think the drop in average skill is mostly a product of the growth in the number of programmers. I imagine that if the ability to sculpt a basic statue suddenly became really valuable, the skill level of the average working sculptor would plummet.
More layers of indirection in a system and more dependencies on external libraries and tooling does not necessarily get you any abstractions. To take a contemporary example, there is no "abstraction" in being driven to use Docker because your dependencies have gotten unmanageable otherwise.

So if Netflix has a "User logon" service, and a "payment processing" service, used across their clients clients you might be looking at a couple of "microservice"s with hundreds of related employees. Imagine services for Googles search autocomplete, ML, or analytics...
As the article states the "micro" aspect is mostly in terms of deployment responsibility, freeing those 10-1000 employees from thinking about the totality of Googles/Netflixes' operations before rolling out a patch :)
It’s 8 or so but it’s possible for me to handle it all. If we add features they’re going to be new services, so adding big features to the services I manage is unlikely. It is more likely that I get a new service on my plate in 6 months time than getting additional members of the engineering team to work on already completed services.
I’m obviously not entirely alone... I’ll ask for help if I need it, and I help out with other people’s stuff too, but I am primarily in charge of them and I am responsible for keeping everything working well.
If it takes 10 people to manage one service, it is not a microservice by definition. It is more like a 10x-microservice or a macroservice.
The definition isn't small teams, per se, it's a small area of responsibility with singular focus. A lego block instead of duplo. That lends itself very well to small teams, but you could reasonably have 100 people working on a service and call it "micro".
Reason being: if those 100 people weren't working on their scoped 'microservice' they would be part of a much, much, much larger pool working on the shared 'product', 'platform', or 'service' that contains that exact same functionality, only without the clarity/scalability of application boundaries surrounding the individual service components.
That's not to say microservices are ideal, just that the size of "micro" is highly relative to ongoing operations.
One developer can certainly be responsible for coding many microservices and even maintaining them depending on the scope, number of users, etc.
Sometimes people might even rotate with a core architect coordinating how they all interact and if they are consistent with each other.
Discussing about microservices can be very confusing if people are thinking about different things and, as always, when there's a good idea implemented in a specific context and people who don't use it get exposed to it as a silver bullet we'll end up with a huge backlash like in this article.
And it's just one of many.
