The curse of knowing how, or; fixing everything

This happens on an organizational scale as well.

Once a company grows beyond a certain point it no longer needs to keep a razor focus on the core business, and a disproportionate amount of effort gets redirected to creating sometimes useful but often completely pointless and gratuitous internal tools. That way every middle manager gets to justify an ever growing number of reports and make his mark in the organization.

I think another important view is to consider how much you've already covered. As a young developer, I recommend spreading a bit wide. Try many technologies. Play with a new language every year. Focus on things you haven't done before, like, don't go from Python to Ruby, go from Python to C# or C++ or something.

But as you get older you want to shift from exploration to exploitation. It is hard to make progress on anything, both professionally and personally, if it first comes with another couple of person-weeks of learning something new, let alone person-months. Even though I find learning new things easier than ever because of the breadth of things I have covered, I find myself having to be ever more skeptical of what I will invest in in that way, because unlike a fresh developer with no skills who has little better to do than learn their toolset, I have skills that can be exploited to good effect. As a mature developer, I need to trade off not so much "what might this be useful for in the future versus the effort of learning now" but "what could I be doing right now with the skills I have rather than learning something new".

Particularly when the "something new" is a variant of a skill I've already picked up. It'd be great if I never again had to learn a devops deployment system. I've already had to learn three. Unfortunately I doubt I'm going to get away with that. It'd be great if I didn't have to learn another scripting language to do something, but I doubt I'll get away with that either. Your mileage will absolutely vary but it'll be something.

I know there's a memeset of the "old fogey who doesn't want to learn", but I really do see the learning costs now as the opportunity cost of using that time to exploit the ones I already have, rather than just grumbling about learning in general. At the moment the things I can't escape even if I try have been plenty to keep my learning skills well-honed.

So bear in mind that as you round out your skills, as you cover "scripting" and "static language" and "database" and "HTML" and "devops deploy" and "shell scripting" and "functional programming" and all the other categories you may pick up over time, it is natural and desirable to pivot to exploitation being more of your time than learning.

After all... what is all this learning for, if not to exploit the skills to do something, not just learn the next skill, then the next, then the next?

This has a name, it’s called CLS (cumulative layout shift) and Google actually penalizes SERP rankings for pages with bad CLS. More info on it on lighthouse.dev (if I recall the domain correctly).

I'm getting a 404.

your comment made me think of a passage in Italo Calvino's Invisible Cities:

Kublai Khan does not necessarily believe everything Marco Polo says when he describes the cities visited on his expeditions, but the emperor of the Tartars does continue listening to the young Venetian with greater attention and curiosity than he shows any other messenger or explorer of his. In the lives of emperors there is a moment which follows pride in the boundless extension of the territories we have conquered, and the melancholy and relief of knowing we shall soon give up any thought of knowing and understanding them. There is a sense of emptiness that comes over us at evening, with the odor of the elephants after the rain and the sandalwood ashes growing cold in the braziers, a dizziness that makes rivers and mountains tremble on the fallow curves of lhe planispheres where they are portrayed, and rolls up, one after the other, the despatches announcing to us the collapse of the last enemy troops, from defeat to defeat, and flakes the wax of the seals of obscure kings who beseech our armies' protection, offering in exchange annual tributes of precious metals, tanned hides, and tortoise shell. It is the desperate moment when we discover that this empire, which had seemed to us the sum of all wonders, is an endless, formless ruin, that corruption's gangrene has spread too far to be healed by our scepter, that the triumph over enemy sovereigns has made us the heirs of their long undoing. Only in Marco Polo's accounts was Kublai Khan able to discern, through the walls and towers destined to crumble, the tracery of a pattern so subtle it could escape the termites' gnawing.
