I genuinely don't understand why everyone isn't using this yet

Andrej Karpathy, a co-founder of OpenAI, posted a simple idea that hit 16 million views: stop using AI to write code, use it to build a second brain.

You point Claude Code at a folder, drop in any source, an article, a transcript, a PDF, and Claude reads it, links it, and files it into a living wiki of everything you know. It compounds like interest, the more you feed it, the smarter it gets.

Here's the whole thing:

> Install Obsidian, create a vault, open it in Claude Code

> Paste Karpathy's wiki idea file and tell Claude to build it

> Claude makes three folders: raw for sources, wiki for its pages, a CLAUDE.md that runs it

> Drop any source into raw and say "ingest this"

> Ask questions across everything, forever

Five minutes to set up, and you never start from a blank chat again.

Full step-by-step guide with Claude and Obsidian, link below.

@DeepIceValue You lost me with $MSTR

[Ronald A. Echavarria @RonAlexanderEch]

$XYZ I like it a lot. A 50% upside over the next 6 months is reasonable. Millions of people will visit the U.S. for the FIFA World Cup, and Square + Cash App should benefit directly. Bitcoin payment processing momentum should also start kicking in.

[Ronald A. Echavarria @RonAlexanderEch]

I like $MRNA over the next 6–12 months and beyond. It’s one of the most shorted stocks in the S&P, down 90% from its highs, and it only takes a small amount of buying pressure to squeeze this thing back into the $80 range.

[Ronald A. Echavarria @RonAlexanderEch]

In January 2024, the floodgates opened for institutional investors through BlackRock’s ETF and others. The 70–80% drawdowns are a thing of the past. Don’t stand around waiting for one, it’s not coming. $BTC $MSTR

[Ronald A. Echavarria @RonAlexanderEch]

@Cobratate Bitcoin’s market cap is $1.7T. A purchase under $1B is barely a tap on the scale. You want a $10K move? That takes closer to $100B in buying pressure.

5/ With better awareness comes better timing. With better timing comes better outcomes.

1/ My breakthrough was realizing my analysis wasn’t wrong — I was simply early.

[Ronald A. Echavarria @RonAlexanderEch]

4/ The mistake wasn’t the thesis — it was expecting the market to validate it immediately.
