"Level two" ? As if there is a single best way to think and we should all climb towards it? There are advantages and disadvantages to every approach. Find what works in a domain and keep experimenting.
I take it, then, this modern society and civilization wants to specialize in low level technician style work and wait for aliens or angels to come and do the hard work of inventing faster than light travel? You know, intuition is the best scientists and engineers can do and all.
No one is saying we shouldn't also have other kinds of intelligence. You just started bashing one kind of intelligence, and provided quite possibly the absolute worst possible example.
Thought, in the general sense, isn't a solved problem or even all that clearly understood yet. We don't yet have a working mathematical model of it and aren't even sure that will be a thing. At present we know of many kinds of intelligence and we can see then work differently on different problems.
Quantum mechanics is a magical system, to you, only because you're limited and guided by your human biases and preferences. Dumping intuition is the way to go for seeing past the toys and child's play that is modern science, technology, engineering, and mathematics.
The theory of special relativity showed how to transform the physical quantities between inertial reference systems, i.e. systems where Newton's law of inertia is true. The relative velocity between the origins of such systems must be constant and there must be no relative rotational movement between them.
The theory of special relativity was not applicable to non-inertial reference systems, like one that has an accelerated motion relative to an inertial system.
Einstein's quest has been to find the transformation relations for this more general case. Together with the theory of the stimulated emission of radiation (1917), this has been the most original part of Einstein's work, because the previous transformations of the special relativity had been discovered before Einstein, he had just given a new explanation for them.
The only intuition related to general relativity was the guiding principle that whatever transformations will be found they must lead to indistinguishable local behavior of the forces of gravity vs. the forces of inertia.
It's a simple equation: take away intuition and you're left with revolutions in technology and science.
