Typewriters are not going anywhere, they are here to stay.
Sadly, it didn’t work that way. Typewriters now have their place in the museum along with the floppy diskettes and video cassettes.
Resisting change is futile, seek out what works and what is next and align with it.
I agree that there is a lot of hype and false prophecies out there, people hype a new technology, programming language or company every week and such fails to deliver over time. But for people who watch the trends, search for and analyse the data for ourselves by ourselves, we can see what is coming up next.
Therefore, if you pull up the data and it suggests a trend, then jump ship! People who where paying attention definitely knew the typewriter was on its way out, but rather than wake up to reality, they clung on to the past.
If the data today suggests that ads do not do so well on mobile, we can fix it by thinking up new advert formats or thinking up new revenue models for our businesses altogether. We do not fix it by insisting Google (an old-era Internet company) made billions through advertising and we are next in line!
Only fools (or special people with uncommon insights) argue with the data. So, except you are a fool or a very talented person, just stick to the data and you will be fine.
