Sun was once a great company, they had a 30 year run. The management team ran the company into the ground, bloated costs and poor decisions. Finally it got sold for cheap to Oracle. Today, most servers are Linux or in the cloud, nobody cares about Sun. Their best assets were people, some of whom went on to do great things.
VMware will end up the same way. Didn't even get to 30 years, 20 years and they were sold at a big discount to their peak price, to Broadcom. Most workloads will move to public clouds. Very few customers will use ESX in 10 years. No one will care about the other products the company had, eg NSX, Tanzu. They will dissolve into oblivion.
The graveyard of once good tech names - DEC, Sun, Blackberry, CA, Symantec, VMware.
