🕹 Technology Artificial Intelligence Machine Learning Open Source Pricing Benchmarking Product Strategy
  1. Cheaper, equally intelligent open-source models still capture under 30% of usage, which shows price and benchmark scores explain only a small part of why people choose models.
  2. Most users pick one model and stick with it, and price cuts mainly shift volume rather than grow revenue, so being a user's primary model creates strong lock-in.
  3. Benchmarks miss key, hard-to-measure factors like trust, safety, privacy, tooling, and support, so differentiation on intangibles matters and tokens aren’t fungible.

Disillusioning the Magic of the fork System Call

Confessions of a Code Addict • 649 implied HN points • 26 Nov 24
🕹 Technology Programming Software Operating Systems Computer Science
  1. The fork system call creates a new process that is a copy of the parent process, but each can follow a different path after the call. This is why a program can behave differently depending on which process it is in.
  2. When the fork call is made, the operating system needs to return distinct values to both the parent and child processes. The kernel sets the return value for the child process to 0, while the parent gets the child’s process ID.
  3. System calls are handled in the kernel, which means understanding their low-level operations helps us see how programming languages like C manage processes, revealing the complexity hidden behind simple function calls.

Six Reasons Why Current AI Won't Displace Lawyers

Autonomy • 34 implied HN points • 20 Dec 25
🕹 Technology Artificial Intelligence Automation Legal Tech Labor markets Regulation Ethics
  1. Current AI doesn't generalize or perceive the world like humans, so it misses novel facts and real-world cues that lawyers use to build and win cases.
  2. Litigation is inherently adversarial, so both sides will adopt AI and the human lawyers who best direct and strategize with those tools will decide outcomes.
  3. Lawyering involves client counseling, moral responsibility, and institutional rules that AI can't fulfill, and greater AI productivity may actually increase demand for legal services rather than eliminate lawyers.
