At the minute, a true open source and free browser/web engine, though I know this is nigh impossible to maintain without thousands of people. Some part of me is hopeful though given recent events.

The problem with Element as it compares to discord in my experience of showing it to discord-heavy users is that it does not contain the feature set that they are seeking.

Discords roles and permissions abilities, multiple channel types, streaming capabilities, public bots that are easily joinable, profile customization features, moderation capabilities, and more have no real equivalent in Matrix/element. Hence, when I have shown it to discord users before, they have 0 interest in using it because for them it is like reverting to an IRC.
