Python calculations run in the Microsoft Cloud, with the results returned into an Excel worksheet.
That’s an instant non starter for me.
Not to mention this integration seems very much focused around the graphing libraries of python and not using it for data processing. It’s not the ‘excel powered by python’ I dreamed of.
I think it's just the first step since VBA is in a dire need of a replacement.
Around the time Office 365 rolled out and replaced Office 2023 at my old job we've had a crapload of old VBA tools just refuse to work. Those tools were in use for 10-15 years sometimes with barely any maintenance required.
Then with O365 some calls to certain 3rd party libraries resulted in Excel crashing without any single error message, stack, nothing. At that time everyone understood they need to get off that ship ASAP, corporate policies got super strict on end user created stuff. PowerBI and Power Automate are not there to replace it and I think MS feels threatened.
