Ok but is there anything one can do in the past that might be able to ameliorate problems that exist in the future like an investment “fund” that can be contributed to as a safety plan when the moment of future time travel intervention occurs so as to alter the suspected future of the future time traveler who may be facing an existential threat?

In other words if there is a time war in the future, what can someone in the past do to get a head start besides understanding the message from the Singularity?
