&lt;p&gt;The reality for most people - even expert programmers - has been that the freedom is more about being able to lean on &lt;em&gt;other people&lt;/em&gt; to do that. Most people can't justify the time commitment needed to read and then modify the code for tools they use very often.&lt;/p&gt;
&lt;p&gt;I think LLMs have changed that equation in a way that makes the original dream much more feasible.&lt;/p&gt;
&lt;p&gt;Several times a day I'll prompt regular Claude chat to "Clone x/y from GitHub and tell me how Z works".&lt;/p&gt;
&lt;p&gt;Getting software to compile in order to start hacking on it used to be enough friction that I often wouldn't bother. Now I treat that as a zero time investment challenge: tell Codex or Claude Code to checkout and build X and then come back ten minutes later and see how it got on.&lt;/p&gt;
&lt;p&gt;I'm not habitually &lt;em&gt;modifying&lt;/em&gt; the software I use yet, but I can see a path to that which didn't exist a year or so ago.&lt;/p&gt;</summary><category term="hacker-news"/><category term="open-source"/><category term="ai"/><category term="generative-ai"/><category term="llms"/><category term="ai-assisted-programming"/></entry></feed>
