I liken it to the Ikeaficiation of furniture. To a great majority, such as my college self, it was preferable and desirable. As I've made more money, I've wanted something better.

There's a market for both, but the furniture slop of Ikea is dominant.

> Enabling new business models

This is true, but only for the bigger players. The nature of hardware still fundamentally favors scale and centralization. Every hyper-scalar eventually gets to a size that developing in-house CPU talent is just straight up better (Qcom and Ventana + Nuvia, Meta and Rivos, Google's been building their own team, Nvidia and Vera-Rubin, God help Microsoft though). This does not bode well for RISC-V companies, who are just being used as a stepping stone. See Anthropic, who does currently license but is rumored to develop their own in-house talent [1].

>> While this flexibility could cause problems for the software ecosystem...

"While" is doing some incredible heavy lifting. It is not enough to be able to run Ubuntu, as may be sufficient for embedded applications, but to also be fast. Thusly, there are many hardcoded software optimizations just for a CPU, let alone ARM or x86. For RISC-V? Good luck coding up every permutation of an extension that exists, and even if it's lumped as RVA23, good luck parsing through 100 different "performance optimization manuals" from 100 different companies.

> How mature is the software ecosystem?

10 years ago, when RISC-V was invented, the founders said 20 years. 10 years later, I say 30 years.

The nature of hardware as well, is that the competition (ARM) is not stationary as well. The reason for ARM's dominance now is the failure of Intel, and the strong-arming of Apple.

I have worked in and on RISC-V chips for a number of years, and while I am still a believer that it is the theoretical end state, my estimates just feel like they're getting longer and longer.

One of many things that bums me out about AI is whether content I create will be truly appreciated by humans, or will just be fed back into the algorithm.

I often wonder how exactly you'd mitigate this. Further, as a user, I wonder what incentive there is for me to write anything at all online, let alone commenting on forums, if it will just be fed back into an LLM.

Is paywalling or forcing user accounts the solution? That feels antithetical to the reason for the internet at all.

Just musings.

If you favor genuine free trade, how do you view the protectionist measures that Reagan put on Japanese car imports in the 80s?

East of Eden by Steinbeck really changed my college mindset on what it means to be "good" and "evil", "right" and "wrong".

It's really hard to describe what the book's about. It's an epic, through and through, and all epics are hard to detail precisely. Inter-generational trauma? Handling one's "sin"? Making a livelihood after repeated failure, be it yourself or external factors?

Contrary to my first sentence, there is one character that I would describe as pure evil. But I feel that just supports one of the conflicts; however incredibly rare, what can an individual do when they come across a bonafide force of evil?

It is dripping with Biblical imagery, and Steinbeck's prose is rambling and tangential for some (though poetic for me), and his characters are not "realistic" and larger than life (but that's what makes them pop off the page for me and so memorable. I guess it's always a balance).

"Now that you don't have to be perfect, you can be good."

Hopefully this is not too tangential, but it's something that's been on my mind a bit recently.

When you had kids (or I guess anyone who is considering having kids), did you ever fear of "passing down" your trauma?

I feel that us tech workers, for all intents and purposes, have "made it," which might best position us in general to overcome and prevent a cycle of trauma to the next generation.

I'd like to work on my writing skills. Some mix of nerdiness and personal Journaling. https://dynomight.net/ is a website that I'm quite inspired by, as it's a interesting mix of personal commentary (https://dynomight.net/advice/) and deep data dives into e.g. homelessness and seed oils.

My main barriers are 1) writing discipline and 2) some obsessive need to link/cite every claim I make. This results in me taking months to write an article, be it due to laziness or constant rabbitholes/google scholar searches about an idea.

Any clue on dedicated disciplined writing time or even considering "reducing" the rigor of writing?

I've definitely had this thought about this sort of openness that RISC-V inherently promotes.

Sure, anybody can make a RISC-V CPU, but who really has the capabilities to verify them?

There's a reason the ARM model has succeeded-- that is, providing totally off-the-shelf IP with pre-verified cores (because of their own large verif team). The logical end of RISC-V is that we have custom cores literally everywhere, but verifying them is quite costly.

The (equally) hard part with CPU design is funnily enough not in creating the design, but the verification. (That's kinda one small reason why I think CoPilot-esque tools haven't permeated the hardware design space very much).
