A thesis is more a proof that you can handle a particular type of research or investigation. I myself haven't touched the particular specialised field of my thesis since I submitted it.
It also doesn't mean that the Author particularly enjoys or finds the topic that interesting. I've often heard that if you have a favourite topic, you should at best find a thesis topic that is adjacent or related, and I'd tend to agree.
