All you have to do is provide an environment in which they can, provide a raise as and when they "level up", provide infinite caffeine, interesting problems, and the rest, as they say, is history.
I'm basing it on personal experience of having grown a company from nothing without funding to an enterprise carrying over £1bn of client commerce in 6 years. But what would I know.
Oh, and 100% client retention and no marketing except word of mouth. I'd say that's satisfaction.
Sure, it's likely not universally applicable, however you shouldn't underestimate the power of an open mind.
I'm not sure your ideas are quite as bold and radical as you think. In fact, I would say that you're merely repeating the common liturgy of the industry. Young tyros are more "creative" than seasoned veterans. Caffeine addled youths have more exciting ideas. They have fewer preconceptions. They're more nimble. They're in it for love of the game.
What I'm asking is why you're so sure all of this is true. "It's true because I am successful" doesn't seem to me very persuasive.
I've worked both in orgs with "greybeards" and in the org I've founded along with many clients. There's plenty to be said for veteran levels of experience, but this is something that's only really needed in a leader, as this experience can be communicated and demonstrated to others. A fool learns by his own mistakes, a wise man by those of others. I suppose this makes me a fool, but a fool who's decided to help others be wise, and to harness those several decades of experience in such a fashion that it benefits all involved.
So yes, you have a point in that years of experience are indeed valuable, but I would argue that this is not a prerequisite to be an exceptional engineer, and that in fact truly exceptional engineers arise through memetic experience, and a thirst for knowledge.
It's true that I speak from personal experience, but then again, so does every scientist who finds a repeatable experiment. I'd be happy to be disproven, but until then, I'm equally happy to treat what I find to be a valid theory as fact.
Young, passionate individuals make the world go round. You only have to look to the great leaps and bounds of science to witness this in visceral actuality.
I thought for a while what is best to say, but perhaps I'll just go with a counter-example: Intel. The founders were around 40 when they started the company, and experienced in their industry. Not the 25 years mentioned above, but I'm taking that as a hyperbole.
If it takes a young, creative individual to create a 1 billion pound company in 6 years, what does it take to make a 54 billion dollar company in just over 40 years?
This has typically arisen from working with existing OSS projects which incorporate vector transforms and the ilk in ASM, often badly or subtly brokenly, and from building optimised functions for doing fun things like creating n-dimensional maps of customer/product relationships in order to determine purchase propensity based on cluster profiles.
So yeah, ASM in a web shop. Except we're only kinda a web shop these days - client sites are our marketing platform, but our business is business systems.
