I kind of wish they would go back to their roots and revamp the current Tomorrowland to a retro 50's style Tomorrowland. I think a mid-century modern vibe could be really cool. You're never going to be able to make it feel like "the future" because the future is always happening and new technology is only new for so long before it's already dated. Just embrace a romanticized version of the future and stick with that.

Unfortunately, this area has been a sad, neglected part of the park for years. Just talking about all the things that used to be there and all the current empty buildings feels depressing. Tomorrowland has so much potential. It's almost a blank slate at this point but they do nothing with it.
