Good point about the M x N problem reduction, but this glosses over a critical limitation. While MCP does turn integration complexity from M x N to M + N for the protocol layer, authentication and authorization remain stubbornly M x N problems.

Each MCP server still needs to handle auth differently depending on what it's connecting to. A GitHub MCP server needs GitHub tokens, a database server needs database credentials, an email server needs SMTP auth, etc. The client application now has to manage and securely store N different credential types instead of implementing N different integrations.

So yes, the protocol complexity is reduced, but the real operational headache (managing secrets, handling token refresh, dealing with different auth flows) just gets moved around rather than solved. In some ways this might actually be worse since you now have N different processes that each need their own credential management instead of one application handling it all.

This doesn't make MCP useless, but the "M x N to M + N" framing undersells how much complexity remains in the parts that actually matter for production deployments.

Just my opinion but, server‑side rendering never really went away, but the web is finally remembering why it was the default. First paint and SEO are still better when markup comes from the server, which is why frameworks as different as Rails + Turbo, HTMX, Phoenix LiveView, and React Server Components all make SSR the baseline. Those projects have shown that most dashboards and CRUD apps don’t need a client router, global state, or a 200 kB hydration bundle—they just need partial HTML swaps.

The real driver is complexity cost. Every line of client JS brings build tooling, npm audit noise, and another supply chain risk. Cutting that payload often makes performance and security better at the same time. Of course, Figma‑ or Gmail‑class apps still benefit from heavy client logic, so the emerging pattern is “HTML by default, JS only where it buys you something.” Think islands, not full SPAs.

So yes, the pendulum is swinging back toward the server, but it’s not nostalgia for 2004 PHP. It’s about right‑sizing JavaScript and letting HTML do the boring 90 % of the job it was always good at.

This is spot on for 99% of companies out there.

I had this happen to me today, at first they claimed it was linkedin, turns out it was a company called "Rocket reach" rocketreach.co. They mine data from everywhere and you have to "claim" your profile to submit a takedown request.
