The whole point behind it was that everything was too slow to handle it efficiently themselves in an uncontrolled manner. When networks and computers got faster we started using ethernet.
Yes, and it's also that switches got cheaper so most new installations only connect two nodes with a single physical conductor.
The whole point was that cs/ma (check if anyone is talking while you're talking) was a competing strategy to token ring (everyone can talk in their turn).
You could lose most of your bandwidth under contention with csma, it scaled poorly and routers/switches were crazy expensive because they needed to have memory to buffer packets at full flow.
Somebody made an integrated switch ASIC and the price plummeted and suddenly every network was switched.
