Simulators have developed considerably in the last $50$ years. These days, most of flight training is done in a simulator and not the actual aircraft. How do you feel about pilots that get certified in an aircraft with only $10$ hours in the aircraft?

In a $2-3$ page paper $($not including cover and references pages$),$ identify the types of simulators currently available to developing pilots, and discuss how each type of simulator may contribute benefit to a pilot's overall flight training program? What are some things that are hard to simulate? Are there other viable options beside either simulations or actual flight time? Be sure to defend your positions with credible research.
