Actually Dan Larimer has nothing to do with it. It's his nefarious dad.

Bitcoin Unchained - The Platform Independence Movement

Oh, and the upgrade can happen this summer if some other fork makes the first move. BTC-U will run on BitShares which has been running at 3 second block times and thousands of transactions per second since 2015. It currently holds a record for most transactions processed in a day that is bigger than old bitcoin and new ethereum combined.

It would take less than an hour to have BTC-U trading in real time globally against all the other assets on the BitShares industrial grade decentralized exchange and smartcoin factory.

I've got an itchy trigger finger. Please - just let some other Bitcoin faction make the first move for their gun.
