He Sold Software to Microsoft for $50K – It Became a $1T Company | Ep 34

They sold their software to Microsoft for $50,000.
It became part of a trillion-dollar outcome.

In this episode of Inside the Silicon Mind, Jim Harding – who was there at the birth of the personal computer – shares what really happened behind one of the most important moments in technology history.

But this isn’t just a story about Microsoft.

It’s about how inflection points actually work – and why most people miss them while they’re happening.

From the rise of the IBM PC to today’s shift toward AI and autonomy, this conversation breaks down what’s really changing – and how to recognise it before it’s too late.

Key Topics

• The real story behind the Microsoft / IBM PC deal
• What an inflection point actually is
• Why most companies miss major shifts
• Platform strategy vs product innovation
• AI vs autonomy – what’s actually changing
• The concept of “Layer 8” of the internet
