There is no need for scaling. Fees will determine Priority.
People that want quick confirmations can send high fee. If you don't care, then you can send low fee. Plus once Bitcoin is more mainstream there will be more micro-payment solutions and alt coins to handle dust transactions.
Just calm down everyone, Bitcoin is working great!
Thanks for calming down everyone. Due to the problems with slow transaction confirmation many are in fear and in panic. If this keeps up then bitcoin users will leave bitcoin and that will be the end of it. But if we all become positive thinkers then we can finally reach that phase wherein transactions are a lot more faster and it will be in the mainstream.
