Have you watched sail gp or the recent America's cups. The racing is as incredibly exciting to watch and the skills of the sailors is a huge part of it. I'd argue that technology was always a huge part of sailing, but compare that to many of the "old" America's cups and now you'll see the racing is so much more exciting (largely because while technology is at the forefront, the rules make boats technologically advanced, but also comparable enough to each other).

I'd also argue that sailors (and particularly skippers) are still celebrities (within the sailing community). Now where you're right, is that that these boats are not accessible to the average sailors anymore, but it is because they require so much skill to sail.
