Orbital mechanics begs to disagree about a Mars colony in 10 years. Drug discovery has many steps that take time, even just the trials will take 5 years, let alone actually finding the drugs.
Science is not ideas: new conceptual schemes must be invented, confounding variables must be controlled, dead-ends explored. This process takes years.
Engineering is not science: kinks must be worked out, confounding variables incorporated. This process also takes years.
Technology is not engineering: the purely technical implementation must spread, become widespread and beat social inertia and its competition, network effects must be established. Investors and consumers must be convinced in the long term. It must survive social and political repercussions. This process takes yet more years.
