We can't even be sure whether GCP itself will be around in 3 years:
> In early 2018, top executives at Alphabet debated whether the company should leave the public cloud business, but eventually set a goal of becoming a top-two player by 2023, according to a report from The Information on Tuesday. If the company fails to achieve this goal, some staffers reportedly believe that Alphabet could withdraw from the market completely. [1]
That's disputed and is not hard data, but there's not any positive reason to believe that GCP will exist after 2023 either.
