> The article argues that our very sense of what counts as "better" or "compelling" is shaped by the assumptions baked into C-style hardware.

And this is where I disagree. History is rife with disruptive technologies that blew the existing systems out of the water.

When we do find compelling efficiencies in new designs, we adopt them, such as DSPs and GPUs - which are NOT sequential or imperative - they are functional and internally parallel, and offer massive real-world gains; thus their success in the marketplace.

We also experiment with new ways of computing, such as quantum computers.

There's no shortage of attempts to disrupt the CPU, but none caught on because none were able to show compelling efficiencies over the status-quo, same as for Colemak and DVORAK: they are technically more efficient, but there's not enough of a real-world difference to justify the switching cost.

And that's fine. I don't want to be disruptively changing things at a fundamental level just for a few percent improvement in real-world efficiencies. And neither are the big boys who are actively developing not only their own silicon, but also their own software to go with it.

The article itself reads a lot like a Post hoc ergo propter hoc, in that it only allows for the path of technological progress to exist within the bounds of the C programming language (while also misattributing a number of things to C in the process), but completely discounts the possibility that how CPUs are designed is in fact a very efficient way to do general purpose computing.

Market success does not necessarily prove conceptual neutrality; it just shows which designs fit best within the existing ecosystem of compilers, toolchains, and developer expectations. That is the lock-in the article describes.

Calling the argument post hoc ergo propter hoc also misses the mark. The author is not saying CPUs look this way because of C in a simple cause-effect sense, but that C-style abstractions and hardware co-evolved in a feedback loop that reinforced each other’s assumptions about efficiency.

And I do not think anyone is advocating "disruption for disruption's sake." The point is that our definition of what counts as a worthwhile improvement is already conditioned by that same co-evolution, which makes truly different paradigms seem uneconomical long before they're fully explored.

We'll have to agree to disagree, then. Technologies such as the GPU provided such massive improvements that you either had to get on-board or be left behind. It was the same with assembly line vehicle production, and then robot vehicle production. Some technological enhancements are so significant that disruption is inevitable, despite current "lock-ins".

And that's fine. We're never going to reach 100% efficiency in anything, ever (or 90% for that matter). We're always going to go with what works now, and what requires the least amount of retooling - UNLESS it's such a radical efficiency change that we simply must go along. THOSE are the innovations people actually care about. The 10-20% efficiency improvements, not so much (and rightly so).
