Devaluation of Avios?

I hear talk about a devaluation of Avios in the future, what truth is there to this and how do you think it would occur?

I currently have around 24k Avios sitting in my account, with plenty more to come with my upcoming trip… but not sure how long I should save for? Was originally planning to try and save for a 2x Club reward seat somewhere, but as I mentioned I’m hearing from some YouTubers that there may be a devaluation, so I’m not sure how long to save in case it does happen I would have missed out on just using them on economy European short haul reward bookings?
