> the main challenge has been training developers to Ocaml and I doubt they would write new code in it now

Why do I never hear about these kinds of opportunities? I have done some Ocaml, quite a bit of embedded systems, and these days I have to waste the years doing web development.

Where do I have to call to be considered for doing OCaml embedded systems?

After 25 years, their production has dropped to 80%.

Unlike what you imply, they don't explode and you have to replace them all. They just keep producing, but less.

And the US subsidizes corn and attacks other oil producers. And Korea puts tariffs to benefit their local technology industry.

Welcome to the real world. Whoever isn't cheating is losing.

I have been following this development for a couple weeks, and now it's on HN. How long until the elevator guy tells me about it?

With tens of thousands in a meeting, cracking a 30-second stupid joke is probably costing several thousand dollars.

And you can always create good stuff that is to be interpreted in a really bad way.

We were told the "paperclip maximizer" as a cautionary tale. Instead, we constructed the "valuation maximizer".

But, for a split second, it generated so much value for the shareholders...

That's why you hire a CSO: Chief Scapegoat Officer.

You pay them a million per year, and fire them when a breach happens.

Way cheaper than improving security.

"We are aware" can mean "we are taking this very seriously and have seen very little so far" or it can mean "after covering our eyes and plugging our ears we are seeing and hearing very little of this problem".

When the expectation is 100x, then it is work 100% of the time at maximum speed.

Tests check the operation for a single value of the, potentially infinite, input space.

Types check the operation for many, and can be made for all possible input values.

The difference is:

None of these boxes contain bicycles because:

* With tests: we checked 3 of them and found no bicycles

* With types: all the boxes are too small to contain bicycles.

The initial part of an S-curve looks a lot like an exponential. The final part doesn't.

Finding the second and the third antibiotic for non resistant bacteria may be fast and easy, finding another three antibiotics for resistant bacteria decades later is now crazy hard, as bacteria evolved to resist everything that doesn't also kill humans.

Hi CEO, thanks for the input. Next time that we have a discussion, we will ask Claude instead of discussing with who wrote the offending code.

Because every time you run the LLM it will generate a new library, with new and surprising bugs.

It's better to take an existing, already curated and tested library. Which, yes, may have been generated by an LLM, but has been curated beyond the skill of the LLM.
