Replacing all the IEEE 754 hardware with posits won't fix this, though.
If you don't care about performance, then the actual solution has no dependency on hardware:
1. Replace the default format for numbers with a decimal point in suitably high level languages with a infinite precision format.
2. Teach people using other languages about floating point and how they may want to use integers instead.
The end. No multi-generation hardware transition required.
IMO, IEEE 754 is an exceptionally good format. It has real problems, but they aren't widely known to people unfamiliar with floats (e.g. 1.0 + 2.0 != 3.0 isn't one of them).
