Runaway inflation? Maybe I'm sheltered here in Canada (although I suspect our numbers are very similar to those in the US). While fossil fuel prices remain volatile, overall, inflation in my country has averaged between 1 and 2% the last several years. Back in the early 1980s, inflation was in the mid-teens as a percentage.
Film prices are going up fast, but they are a small part of the economy, and consumer electronics generally go down in price as time moves on.
Film prices will stabilize at some point, assuming silver prices and oil prices stabilize too (film base is a fossil fuel product, and films obviously have to be shipped from their point of manufacture to the consumer), but film photography is always going to be a little expensive compared to digital, the same that fountain pen ink is expensive compared to cheap, disposable ballpoint pens. The market has changed, but the prior option will remain for those who want to pay for it (like us).
