That sounds horrible. We should focus on making good products that last a long time. What is the point of making something new and almost identical every 5 years?
How long did it take to upgrade from IPV4 to IPV6? IPV6 is a massively popular protocol in which virtually every technical person admitted we will need to move off of IPV4. IPV6 is 25 years old and we’re still not done with the migration.
Protocols have a massive problem with updating their feature sets and security features.
If that were so, you would still be in business. The whole thing is products try to continuously evolve, which is what the parent is against. He/she says don't evolve so much that you become a new product. Instead shut shop when it becomes unprofitable and make a new product.
Be THE product for half a decade, make your money, close up, next venture.
