I thought LUX is ASIC/FPGA resistant after they forked to Phi2?
No algo is fpga resistant 
As i have not oredered a FPGA i do hope the LUX team will be able to stay ahead of the FPGA programmers. If they are able to make requirements so you need new FPGA it is like ASIC resistance which is as good as it can get.
But i dont have the skills to do more than hope hehe.
Since FPGAs are programmable and also they can have their memory changed (at least some of the FPGAs I've seen use normal PC RAM), how can a developer make an algorithm that's FPGA resistant and not GPU resistant at the same time?
But most importantly, WHY would anyone do that? FPGAs are like GPUs but capable for anything except gaming. Sure, GPU mining is a bit easier at the moment, but you still have to find the right miner and set the correct clock speeds. FPGAs can be as easy to use in the future.
As long as they're open source and not closed like the ASICs which will be turned into useless heaters once an algorithm change or the manufacturer decides to release a faster ASIC, I don't mind FPGAs taking over GPU mining.
I believe coin developers are trying to keep it fair to everyone, but if their algo is tuned right, it will have the same hashrate/$$$ invested. We just dont want anyone with a 3k$ hardware to crush a 300k$ gpus farm. Theres nothing wrong in being efficient, just make sure its fair, thats all... Up to know ASICs and FPGAs has been seen as unfair thats why theres so much hate towards them, clear this issue and lets welcome more efficient hardware!
