Bullshit. Companies are making decisions on bitcoin right now based on the current 1MB block limit.
Imagine if a large tech company, like Amazon or Apple, were to put their full weight behind Bitcoin by promoting it and offering customers a discount to use it? I think such a move would almost instantly overwhelm the Bitcoin network, and these large companies know that so they won't do it until the Bitcoin network is ready...
What if NASDAQ or the NYSE wanted to record trades on the block chain? Again, right now that is a non-starter and would overwhelm the network.
The internet of things sounds interesting, but again, if IBM or Intel were to put their full weight behind it they could almost instantly saturate the Bitcoin network.
The 1MB block limit is already harming bitcoin.
If you see a very limited bitcoin future where the market cap is small, usage is limited, and people can run a full node on a POS 5 year old laptop with a slow DSL connection, stick with the 1MB block limit.
If you see a future where bitcoin is a worldwide currency with a much larger market cap, where the blockchain is used for smart contracts and to record stock market trades, and where bitcoin is the foundation of the internet of things, bitcoin needs to scale substantially and it needs to start right now...
The core devs need to reach consensus on a scaling solution ASAP before they do irreparable harm to bitcoin. Uncertainty around the max block size is already starting to cause the price to tank.
