Explain the ways (if any) in which you think the measurement of inflation might need to change in a post-covid world, for example in 2025 or a bit later, when most people have presumably been vaccinated and when some of the long term changes (e.g. more working from home, more online services, etc.) are increasingly felt.

Anything, any references , thank you!

Please give some solid points besides CPI, thank you! no need for background information eg what inflation is.
