<p>It uses phase change (solid to liquid) to store heat at about 200 kJ/kg. Compare this to heating water in a boiler from 10c to 60c - stores 209 kJ/kg.<p>So we already have an effective way to store heat which can work for decades without servicing and is also cheap to produce (in terms of money and energy consumption).</p>

<p>LLMs are learning in a very similar way humans are learning. So if humans can read a text (or view a video), learn from it and then use the knowledge to produce something, so can LLMs?<p>Copyright laws have quite strict rules on what constitutes a copy, and this was tested in courts many times. This rules also apply to works produced by LLMs.</p>

<p>You must be using a dynamic language with a heavy framework? Rails maybe?<p>I code in Go mainly (also Java and Rust) and never experienced what you describe: simple addition of a field to a struct does nothing if not used in code. And the use is simply checked by compiler.<p>However, I did work alongside a Rails team which had major gripes with this. They called it brittle tests: whenever they made a simple change (like adding a field), half of their tests would fail. This really lowered devs' confidence in their codebase and slowed the changes to a halt.</p>

<p>If you are concerned by this proposals, then you should check out current CAs trusted by your browser - all those CAs can issue rogue certificates trusted by your browser, that can be used in MITM attack.<p>For example, CAs present in Firefox, that might give you pause: Beijing Certificate Authority, China Financial CA, Guang Dong CA<p>The CA system in browsers is inherently broken and it allows state actors to MITM you and see all your traffic if they:
  1. have ability to capture IP traffic (requires cooperation with ISP)
  2. have ability to generate rogue certificate via cooperation with CA</p>
