I’m just glad Java applets died.
Phone books would be a definite regression though. I don't want to physically leaf through five pages of AAAlberts and Aarons to find the plumber.
I do still use my local yellow pages every now and then because local tradespeople are terrible about advertising on the internet in general and I don't have many neighbors. But word of mouth is better when you can. The general contractor who will hopefully do a big job for me after a fire is a reference from a local electrician who helped get my power turned back on who was a reference from the deputy fire chief.
That said, while I'm glad to know what pre-internet felt like, no way would I want to go back to that.
Among the things that define my life (partner, travel, education, work, hobbies) almost all have been only been possible because of the Internet.
