Startup programmers really make that much? I thought only the established "big" industries can afford the really high wages (like banks, telco, insurance...).
Its a theorectical average salary. You've got a very large chance of earning nothing or almost nothing and a very small change of being a zillionaire. You get one or more attempts at getting a good outcome. The average outcome would be approximately 100,000 pounds.
Any foundation for that statistic, or is it a wild guess?
Yeah, that seems fishy to me too. Altough i can see an argument about how the high salary is needed to compensate for the lack of job stability.
