Hey👋,
I'm Giacomo

AI use case of the day:

Automating stock market research 📈

Yesterday, I shared a post comparing the AI boom to the Dotcom bubble, backed by an Excel table of data.

I didn’t manually populate that table. AI did it for me.

I used ChatGPT to write a Python script that automatically pulled stock market data and formatted it into an Excel sheet.

How I did it in 3 (extremely) simple steps:

1️⃣ Prompt ChatGPT to write a Python script that retrieves the data I need.
2️⃣ Copy-paste the code into Google Colab (extremely easy tool).
3️⃣ Run the script and download the resulting CSV.

Before AI, I would have taken ages (if ever) to learn Python and debug the script.

Now it took me minutes.

If this isn’t a complete revolution, I don’t know what is.

Oh, and I used Perplexity to find old articles about tech bubbles. Also took me one minute.

"This time is different."

Yes, it actually is.

Despite the recent dip, financial markets are at historic highs.
They are dominated by the technology sector, which brings some people to compare the current situation with the Dotcom bubble of 25 years ago.

Maybe they're right, but...

It's not the first time a single industry dominates the market and it doesn't always end in a bubble.

In 1900 rail was the dominant industry, even more than technology today.
That was justified by the revolution of train transportation around the world.

Just 15 years ago the technology sector represented the same share of global market capitalisation as the financial sector, around 6%.

Now it's around 19%, a massive increase!

But considering AI is just getting started, I'd say this is just the beginning!

AI is indeed a revolution, and a very quick one. It's changing our daily lives as we speak.

In fact, today's AI-driven tech leaders are fundamentally stronger than the darlings of the Dotcom era.

For example, NVIDIA has today a net income margin of 49% vs 17% and 15% of Cisco and Oracle respectively in 1999.

Five out of the magnificent seven have a net margin over 20%, which is generally considered very high. Plus, their net income growth rate is still amazing.

Also, Dotcom companies' valuation was crazy high when compared to today's stocks.

In March 2000, Cisco had a price/earning ratio of 196.2, vs "just" 36.6 of NVIDIA today.

I believe we're just at the beginning of American tech dominance, thanks to AI.

PS
The New York Times already called for a tech bubble in 2014!

The crypto industry in one screenshot 🤣

Trump makes $350m from a memecoin, while the US “strategic” bitcoin reserve doesn’t look so strategic anymore, and more like a marketing stunt.

Btw, Trump is in great company with the presidents of Central African Republic and Argentina who also pumped and dumped their presidential memecoins.

Meanwhile, great projects are being built on Ethereum and other blockchains, but nobody cares because they’re not going to “the moon” 😅

xAI is going to win the AI race.

Grok 3 has a fundamental advantage over competitors:

Real-time information!

Financial markets recently fell and I wanted to know why.

Grok gave me an answer as of "March 5, 2025 at 3.56 AM PST".

If I had prompt it an hour later it would have given me a different answer.

This is a crazy breakthrough!

It mentions several sources including recent X posts, updated to few hours earlier.

Elon Musk sits on a goldmine of real-time data:

- X posts
- visual information collected from Teslas' cameras.

Real time information gives AI the context necessary to act like a human.

Many of our actions are determined by the imminent context rather than previous knowledge or experience.

So should be the actions of an AI chatbot, a self-driving car or a humanoid robot.

At this point Musk has it all:

- the money
- the data (proprietary data, unlike OpenAI which relies on the open web)
- the media
- the political influence
- the factories
- the manpower (thousands of loyal employees)

oh and the marketing power!

"Grok me this" is the new "google it".

Mad!

From GPT-1 to GPT-4.5: from 😂 to WOW!

In just 7 years, Ai went from a joke to mind-blowing.

What about the next 7 years?

‍

2018 - GPT-1: Couldn't even answer a simple question.

2019 - GPT-2: Responses were messy, almost gibberish.

2023 - GPT-3.5: The real breakthrough.

2023 - GPT-4: Set the standard for Ai chatbots.

2024 - GPT-4.5: even smarter, better, almost human.

‍

All of this in just 7 years.

‍

Imagine where we’ll be by 2032 🤯

‍

What do you think the next 7 years will bring?

When you thought the UX couldn’t get more crowded… 😅

‍

OpenAI just dropped GPT-4.5, what’s new?

‍

🔹 It's more "human".

It should better understand how humans think and what they need.

It knows when to engage in deep conversation and when to be "cold".

It’s should also be better at understanding emotions and deep intent.

‍

🔹 Fewer hallucinations.

Larger knowledge base > better at delivering factual information with fewer errors.

‍

But…

GPT-4.5 does not “reason.”

‍

In practice, GPT-4.5 might replace GPT-4o for everyday tasks, while we’ll still rely on o1 and o3-mini for complex problem-solving.

‍

The good news is that OpenAI knows choosing between 9+ models is a nightmare. 😪

‍

In their blog post announcing GPT-4.5, they stated:

"In the future, we will work to simplify the user experience so AI 'just works' for you."

‍

It'll be about time!

Imagine being credited $81tn.

‍

Happy Friday everybody! 🥳

Want to know a secret?

‍

I'll show you how I used ChatGPT to write yesterday’s post.

‍

Not entirely, but enough to save hours of research and polish.

‍

Yesterday, I wrote about how social media is shifting towards paid subscriptions. To back up my argument, I needed a full list of subscription products from major platforms.

‍

Rather than spending hours collecting data, I used Deep Research on ChatGPT to generate a comprehensive table with all the details.

‍

I used a short and simple prompt, no complex prompt engineering here.

‍

I quickly drafted my post, then I ran it through LinkedIn GPT.

LinkedIn GPT is a custom GPT I built by uploading all my past LinkedIn posts (yes, all of them!) plus some content from my favorite creators.

It outputs a refined, high-impact post that still sounds like me.

‍

Many creators want you to buy complex templates and courses on how to automate your life with AI. But this is not the point.

‍

AI doesn’t have to be complicated. If it does feel complex, you’re probably doing it wrong.

It should be so simple that it becomes part of your daily workflow, as a personal assistant rather than a replacement (for now).

‍

How do you use AI in your daily work? 👇

ChatGPT Deep Research is now available to all Plus users!

‍

Two weeks after I got my Pro $200/month subscription 😭

‍

Deep Research was by far the most attractive feature of GPT Pro.

I used it a lot and saved countless hours already.

‍

Soon after its launch, it was copied by Perplexity and included in its $20/month subscription.

‍

Then it was copied by xAI Grok, while Google already had its own version in Gemini Advanced.

‍

GPT Plus gives 10 Deep Research queries per month, which is not a lot, but already enough for most users.

GPT Pro gives 120 queries per month, more than you'll ever need I think.

‍

Now it'll be all about who provides the best Deep Research results!

‍

So far, I have tried GPT Pro and Perplexity and the former still wins.

‍

But we'll see!

💰The internet is going premium.

‍

We're witnessing a fundamental business shift:

‍

The ad-supported internet is giving way to a subscription-based model.

‍

Just look at social media:

‍

‍LinkedIn Premium: $29.99+ / month

‍X Premium: $3+ / month

‍Meta Verified: $11.99+ / month

‍YouTube Premium: $13.99 / month

‍Snap Inc.+: $3.99 / month

‍Telegram Messenger Premium: $4.99 / month

‍Reddit, Inc. Premium: $5.99 / month

‍

Even TikTok is testing an ad-free $4.99/month subscription!

‍

Search is no different:

‍

‍Perplexity Pro: $20 / month (soon launching its own premium? browser)

‍ChatGPT DeepSearch: $200 / month

‍

Soon, paying for a "good enough" version of the internet will be the norm.

‍

This changes everything:

‍

Digital marketing, advertising, website UX, etc

‍

Are we ready for a world where the best online experience comes with a price tag?
