Trace Mayer doing a series of podcasts with Adam Back. they're good to listen to in understanding where the Cripplecoiner's are coming from.
but listening to this podcast on LN, you can easily understand that Back doesn't understand economics or human behavior:
http://www.bitcoin.kn/2015/09/dr-back-on-lightning/
just a couple of select points where he fails to understand, as a technician, that you can't push a single dynamic system variable to its extremes and not expect multiple other variables to start compensating b/c of the economic pressures:
1. he believes that in an unbounded system with no block size limt, there will be a Tragedy of the Commons and refers to a "reddit comment" where miners will crawl all over themselves to mine 0 fee tx's until the system implodes. TOC discussions have been going on over at BCT since 2011 when the price was under a dollar. first off, there are no 0 fees; Bitcoin has a minimum fee of 0.0001 BTC. also, at some pt there will be an equilibrium where enough miners who overmine at a loss will in fact implode and go out of biz. then, difficulty will decrease. as these miners fall out and difficulty drops, eventually new miners will step up to fill the void and take advantage of the lower difficulty. their motivation? the lower difficulty, improved efficiency, and the ongoing fixed currency supply whose value should continue to increase as more and more fiat gets printed. Bitcoin has already proven that the TOC is false.
2. he says, matter of factly, that bigger blocks yield less security. again, single variable simplistic thinking. a will cause b with no consideration of anything else. on the contrary, as more throughput is enabled by bigger blocks, more user growth and fee paying tx's will be put through the system. he never mentions the price reaction which we know should go up as more participants need the currency for their individual usages. we know this has been the historical case from Peter R's long term graphs. the price will also rise from speculators recognizing that the system can indeed grow. if the price rises to $2000, suddenly the minfee of 0.0001 will be worth $0.20 from the $0.02 it is worth now. this will cause an influx of new hashrate as miners are attracted into the higher value system that is now yielding more miner profits. most likely, most of this will come from outside of China where bandwidths are better and new miners will be encouraged to take mkt share from China.
3. he says that the current system needs to stay as is to keep Chinese miners happy. i say that's crazy. the last 6 yrs of Bitcoin history has favored the Chinese miners b/c of their cheap labor, subsidized electricity, and cheaper ASIC manufacturing. by catering to their desires to keep block sizes small, we're allowing Bitcoin mining to remain relatively centralized inside China and for them to keep their current market share. that's unwise, as we never know when the communist gvt might intervene in their mining. we should want to diversify mining outside of China. they need competition. the only way to do that is to allow the system to grow and allow ROW miners to take advantage of the one system variable advantage they have over the Chinese; bandwidth. the Chinese miners are suffering from an artificial constraint called the GFC. bigger blocks will allow miner growth outside of China leveraging that bandwidth advantage and contribute to more decentralization and security of mining away from their communist gvt. so the conclusion is the opposite from the one he derives; security will actually go up from bigger blocks, greater thoughput, user growth, and inc tx fees in aggregate.
there's plenty more in there but these were the top of mind objections i had on a first listen.
