I'm not just talking about the experience of browsing websites, although to compare a typical website in 1999 vs in 2019 is a bit like comparing a model T to a Tesla (for better or for worse). I'm mainly talking about all the services that are available today though, not just serving static text with pretty markup. web search, video streaming, cloud storage, etc. were barely available (to consumers) or non-existent in 1999. I'm venturing out of my area of expertise here, but I believe sharding, cdns, and load balancing were also in their infancy then. big web companies would actually have their sites go down and have meaningful downtime. web services are much more resilient today than they were.
