I've been pushing people to use Element (matrix) rather than Telegram whenever possible but Telegram has that critical mass and beats Element's usability by a mile.
To extend your wish: i wish i had a ton of cash to dump into development of matrix's 3 top most client apps (including Element)...to diversify things, and to ensure they compete with each other for improved UX...and of course to speed towards a more p2p world (at least p2p for messaging). ;-)
