Definitively. Especially if you work in finance there are many products that integrate with Excel (i.e. Bloomberg apps), modules, pre-created formulas, books teaching financial "programming" with Excel etc..
Then I don't know if macros/programming in Calc can be seen as equivalent to VBA (and relevant integrations) in Excel.
BUT, having said that,I think there are tons of users that could use Calc for their basic calculations (I worked in a couple of banks and I think probably just 5-10% of users used it as "powerusers" and I suspect less than half of them used functions/code that have no equivalent in Calc)
