Many different engineers are responsible for the concept behind escalators, originally known as “Revolving Stairs”, created in the late nineteenth century. The idea was first developed by engineer Jesse Reno, but credit was ultimately given to Charles Seeberger after a long series of redesigns and negotiations. Seeberger later partnered with Otis Elevator Co., which coincidentally, remains the global leader in escalator and elevator manufacturing to this day. Improved technology has helped guarantee a safer experience for passengers now, but the simple process has remained substantially the same over the years.

Now

This is incorrect. This word does not signify sequence. Rather, it brings the idea back to modern-day through the phrase, “…has helped guarantee a safer experience for passengers now”.

Substantially

Coincidentally

This is incorrect. This adverb shows something that has resulted somewhat from chance. In the passage, the author notes that “Seeberger later partnered with Otis Elevator Co., which coincidentally, remains the global leader in escalator and elevator manufacturing to this day”. This is an interesting fact highlighted by the author.
