I think that Microsoft will continue in some form regardless of what happens with this bubble because they have huge amounts of physical assets and cash on hand.

That said, their market position in any given sector they’re in might not be as invincible as it seems. There are corporations that were titans of their industries, including technology, that either don’t exist or are ghosts of their former selves all in far less than a lifetime.

Kodak, Xerox, Bell Labs, IBM, and Yahoo all looked like unstoppable juggernauts when I was a kid, and my own kids haven’t even heard of some of them.
