Concerns with his politics aside, I do think there's a truth to what he's talking about here, and that he is just spelling out the reality that developers are, or shortly will be, facing. For many this will be deeply uncomfortable to hear.
It is notable that his perspective in this talk is very much from a developer-user side rather than someone who is responsible for the framework itself. That surprises me, and I suspect it is not a good omen for Rails.
For all of this embrace of agentic development, there is nothing here on how they are adapting the framework for this new agentic development reality. Agents do currently work well with Rails, but there's nothing here pushing things forward as best as I can see.
I know for my own projects I've largely moved to Elixir/Phoenix, for similar reasons to his use of Rust... I didn't want to have to learn it, but now I don't have to and I get to benefit from its strengths.
I literally just patched an AI-generated API endpoint on a new service at work that shipped without any auth whatsoever, because AI was re-implementing the auth token check method individually in each child controller instead of implementing once in a before_action hook. That's Rails 101 stuff and the app is small. It was so obvious that I saw it right away just reading the code, I didn't even set an agent loose to do an initial inspection. It was a real "yeah I still got it" moment for me.
I'm on board with the idea that agents are going to write most of the code, but not checking it is just insane to me, based on some of the things I've seen committed in commercial codebases recently.
One of the strengths of Rails was that it helped developers who maybe didn't always know the "best way" to build things to build in a standards compliant way – not that you couldn't do things like return a 200 for Not Found if you really wanted to etc.
I'm always pleased when working with a dev who has Rails experience even if they've since moved stack, as often they have picked up and learned the value of these good behaviours. Perhaps it's as much a community thing as a framework thing, or combination of both.
Agentic development definitely still has room to improve, but I suspect that there is some future framework (maybe even language) designed to help minimise these types of mistakes.

Maybe there will be one day, but what are the odds that it will meaningfully move the needle for existing platforms such that manual code review is unnecessary? "Blindly trust the output" is not a feasible security posture today.
I still review PRs, but rarely suggest changes. The most meaningful reviews come from our review bots. I mostly review broad architectural decisions as a way to keep abreast of changes in the codebase. There's a cohort of engineers I work with who I would be perfectly okay with letting the clankers review, approve, and merge their PRs. But there's a larger cohort of engineers who need what I would call a directional code review.
