You don't "make perpetual growth," you saturate markets and then have to move into new markets which your existing legacy will often make far more difficult. Look at one of many presentations showing the changes in the top companies by market value over time:

By 2021 five of the top six players are tech companies and four of those five have customer counts measured in the billions (the first Google result said Amazon only has 310M customers.) Cisco has "partners" because they can't deal with a large number of contact points and generally won't warranty anything not purchased through Cisco or a partner, pushing support for all but the largest customers onto the partners. Cisco is still in the top twenty but the lift into the kind of culture it needs to be in the top ten is not something I'd bet any CEO that Cisco could get to take the job could do.
Since Cisco is built mostly from 30 years of acquisitions and every billion in annual revenue growth is now less than 2% growth, Splunk might get you 6-7% growth the first year (ignoring the cost of buying it and any negative growth in the parent) and while Splunk has shown significant revenue growth, in "rounded to one significant digit because we don't know how either will really perform" numbers that will likely be diluted by something like a factor of 10.
