Looking back, it was one of the best things that could've happened to me.

I believe that the entrepreneurial life, even when running a large company, is a dual experience of joy and pain—two sides of the same coin. The joy lies in putting yourself out there and leading an organisation in a specific direction, but with that comes the burden of responsibility.

The brain is definitely not doing computation in the purest sense. We are not crunching numbers in binary ones and zeros in our heads. When people ask me how our system compares to an NVIDIA GPU in terms of FLOPS, I tell them they're asking the wrong question. A more important question is: what are your inputs, what output do you want, and how intelligently can the system get from one to the other?

There's also a great metaphor from the world of automotive technology. The main naysayers against cars were probably the drivers of carriages in the streets of New York. At some point, the Model T factory was open. And suddenly you're looking around, you're looking at the friend that is driving a car and you're saying, wait a second – he doesn't need a barn to house your horse.

It's not just the hostage who suffers, but their entire family. In some cases, families endure greater agony, living in uncertainty about their loved one's fate. For example, during my captivity, my wife was unaware of my survival for three and a half years.
