Also, I’d expect both gradual and dramatic improvement in technology. It took until the middle ages to figure out that people needed left and right shoes rather than an identical shoe for each foot. It took until very recently to figure out how to make reasonably cheap computers and that they should be linked through search engines.
There is no reason to think that we’re close to inventing all the possible cool stuff.
