In 2007 Steve Jobs stepped up into the stage and told everyone how the future would be. Many did not understand or did not believe. Turns out he was right, actually more right than everyone could have imagined at that time, including probably himself.
In the past years Jensen Huang has been doing the same, telling everyone how the future will be. He is the new Steve Jobs. He is different, for sure, but it's the guy who will carry on all of us for the next decade. Many still don't understand though. I think we were in need of a new Steve Jobs.
Actually for today's year (2022) the book is not so much of a great news compared to when it was released (2018). Today almost everyone already understood that software development is done this way (at least the right software development process).
In 2018 for me this was an excellent book, it changed the way our organization positioned ourselves regarding software development, and we are very grateful we did that. At that time, before 2018, the "modern" software development companies were talking about "digital transformation", we were already in the agile world for some years but the book gave us a name to go for, "accelerate".
It's an excellent book and I agree with almost everything that is written in it (I work in the software development business for over 26 years).
I wonder how creative people can be with naming. Coda vs Coda. An editor vs an editor. Three years in stealth and this name... Well, if they change the name in the future, probably it will be... Excel! The new Excel.
As some already mentioned, it's never too late.
I'll add a little bit from my experience, of having started a technology company in my 20s and then, later, starting two others after my 40s, all of them active until now.
The two most important things I felt different were: time and energy.
I explain.
The time I had to work for my startup when in my 20s was huge, almost any time I wanted, and everyday. And that's what I did. I worked everyday, all the time. When you love the company you founded, that's what you want to do.
But now, after my 40s, life changed. Married, children, and a lot of obligations and responsabilities. I definitely don't have the time I had in my 20s to dedicate to the startup. And yes, you need to dedicate time!
Regarding the energy, I mean the energy related to health, physical capacity, intellectual concentration and ability to handle stress. These are all different 20 years down the road. And I amazed now, to see and feel the amount of energy one needs to dedicate to the startup. I had forgotten this.
I'm not commenting all other aspects related to loving what you want to do, entrepreneurship capacity and persistence because I'm taking these as given.
So, in short, if you have the _time_ and the _energy_, go ahead do your startup. Otherwise, go do something else.
