[Discussion] Limitation/ what could go wrong?

Sup fam, Looking for constructive opinion and discussion.

Have a few questions to start with 1) EIP1559 is expected to be around this coming July, so I’m more interested in “what could go wrong?”. Any technical or reality issue that could lead the improvement to fail? What are the things that will be limiting or holding PoW to PoS back? 2) If improvement and algorithmized burnt fees are expected, shouldn’t it be lesser miners now? As the transition will cause them to only earn from getting Eth after mining (compared with the current miner fees)? 3) What if there’s a 51% attack?

Open to more discussion in the comment section so we can go through from the same thread.

TIA.
