First Sylars power is very different from Micah's.
Micah can communicate with machines, as a result he can make them do things even if they can't do so at the time like how he got the "out of order" phone to work. This coupled with his high IQ allows him to fix machines up as well.
Sylar see's how things work and as a result can fix things like a clock, he could probably fix any machine or whatever with his power. But beyond this he can see how people have powers and as a result change his body to have said powers through consumption of there DNA or something else entirely.
Micah's power would never evolve into a power exactly like Sylars.
At most Micah could learn to communicate with living things, controlling them, optimizing them..etc. He wouldn't develop the power to take powers ala Sylar. He might find out what makes people have powers by there bodies telling him such information but its doubtful he could change himself to take/have said power.
Look at Linderman, he can't heal himself but he can heal others. The opposite is true with Claire, she can heal herself but not heal others. So even if we took the giant leap and believe Micah will learn to manipulate living things like technology it still be doubtful he could use said power to allow him to gain powers.
I love how people see Micah pat Monica on the back when he says I wish I could fix you or whatever and now there like ooo he can heal or effect living things or ooo he can become like Sylar.
Its called grasping at straws people...
