I am sure that during our lifetime we will not be able to see the time machine.  Many scientists support the fact that it is possible to create it, but for this we do not have the necessary technologies on Earth, so we do not need to dream about a time machine, but rather focus on correctly perceiving all the information and analyzing it adequately so as not to repeat  such mistakes that we have made since 2009.  I was constantly told about the prospects of Bitcoin, but I did not believe it.  If I were to be more attentive to Bitcoin information at that time, then I would really be a rich person today.
