Veto is being slowly removed from most decision-making procedures. It's already not there for a lot of (most?) "simple" areas. In theory even the budget should be approved with qualified majority at some point in the next 10 years or so, if the European Council follows the roadmap that the previous Commission recommended.

I don't know your lifespan, but in the next 40 years I expect the veto to be limited to mostly symbolic areas, like defense.
