Agreed. Thank god Wifi has never been as bad as Bluetooth.
Bluetooth is like plate spinning. If you can do it, it's impressive.
And in order to get the USB adapter to work I had to install a new operating system (Windows 98SE).
Networking was difficult. I remember having to install TCP/IP and doing magical voodoo with specialised printer cables to get two computers to share files with each other.
Nowadays you just plug stuff in and it works.
