There are a lot of things that younger people in particular take for granted today that were basically not available in 1990. I occasionally think that if I had to go back to 1990 and do my job as a product manager, I'd probably quit in frustration over just not having the information I needed to do my job.
But you'd only be competing against other similarly hampered project managers. Depending on how well you worked without the modern internet, you'd simply find your same place in the bell curve.
