Put the kettle on; it’s another epic data-driven screed from Alex. The footnotes on this would be a regular post on any other blog (and yes, even the footnotes have footnotes).
This is a spot-on description of the difference between back-end development and front-end development:
Code that runs on the server can be fully costed. Performance and availability of server-side systems are under the control of the provisioning organisation, and latency can be actively managed by developers and DevOps engineers.
Code that runs on the client, by contrast, is running on The Devil’s Computer. Nothing about the experienced latency, client resources, or even available APIs are under the developer’s control.
Client-side web development is perhaps best conceived of as influence-oriented programming. Once code has left the datacenter, all a web developer can do is send thoughts and prayers.
As a result, an unreasonably effective strategy is to send less code. In practice, this means favouring HTML and CSS over JavaScript, as they degrade gracefully and feature higher compression ratios. Declarative forms generate more functional UI per byte sent. These improvements in resilience and reductions in costs are beneficial in compounding ways over a site’s lifetime.
Since the early days of the web, large corporations have seemingly always wanted more than the web platform or web standards could offer at any given moment. Whether they were aiming for cross-platform-compatibility, more advanced capabilities, or just to be the one runtime/framework/language to rule them all, there’s always been a company that believes they can “fix” it or “own” it.

An insightful and incisive appraisal of technology adoption. This truth hits hard:
React and the component model standardises the software developer and reduces their individual bargaining power excluding them from a proportional share in the gains. Its popularity among executives and management is entirely down to the fact that it helps them erase the various specialities – CSS, accessibility, standard JavaScript in the browser, to name a few – from the job market. Those specialities might still exist in practice – as ad hoc and informal requirements during teamwork – but, as far as employment is concerned, they’re such a small part of the overall developer job market that they might as well be extinct.
A demonstration of how even reinventing a relatively simple wheel takes way more effort than it’s worth when you could just use what the brower gives you for free.

This is a fascinating way to present a code tutorial! It reminds of Tim’s Tutorial Markdown that I linked to a while back (which in turn reminds me of Bret Victor’s work).
Applying the principle of least power to tools and technologies.
There are many ways to style a cat.
If you’re making a library or framework, treat it like a polyfill.
The perceived state of front-end development tools and technologies might be quite different from the reality.
