What would the inside first floor of an updated Discovery Center even look like? Its ostensibly meant to be an interactive educational exhibit of sorts, and back in the 90s when it was built, they were largely able to do that.
However, at this point, the science has moved on way beyond the depictions in the Jurassic franchise. An updated exhibit would either be elaborate fabrications intentionally presenting complete lies to children as facts, or it would be completely incongruous with the rest of the franchise and land. Neither of those options seem very appealing, so they probably will have to update it to be a completely different sort of attraction.
