You could create similar optimistic charts for US, China, India, etc.
The EU ( 550 million ) tech industry is dwarfed by the US ( 350 million )
Looking from a higher abstract plane, EU produces the least new entrepreneurs and innovative companies compared to the beast that is US and Asia.
The EU also has the most unstable political and financial system globally with entire countries on the verge of defaulting on their sovereign debt.
The reason why every European developer migrates to London is to escape the craziness of the continent.
Every European developer's final 'dream' is to work in the US tech industry - London is the second best thing to reach.
(.. Money Talks .. )
You can see how much value that tech is given in europe by just looking at the salaries in europe vs N.A - so much for valuing hard tech.
Seeing that both the US and Europe have similar numbers of developers (~ 3 mil) - how is european tech industry 1/8 the size of the US ??
Oversupply of developers due to better engineering school ? ( my sides )
More like MBAs from Cambridge are not as smart as their counterparts graduating from Sloan in creating value out of tech.
