Or even human travel.
First of all, we're already doing extrasolar exploration; remote viewing is a form of exploration and we have probes headed out of the system.

Second, STL probes are a likely possibility this century. STL travel (hybernation/generation ships/clone growers) remains a possibility for future generations to engineer.

My primary objection remains to the word NEVER.
Agreed. Never say "never", say "highly unlikely" instead.

As Gordon Woodcock put it, the three methods of travelling to other stars are "go slow", "go fast", and "go tricky." That is,

"Go Slow": travel at low percentages of lightspeed, and somehow deal with the fact that human beings have lifespans of around a hundred years while slow star travel can take thousands of years. There are several methods.

"Go Fast": travel at high percentages of lightspeed. Einstein's time dilation will solve the lifespan problem. The trouble now is that such speeds require absurdly high (dare I say "astronomical?") amounts of energy. They though they had the solution with the infamous "Bussard Ramjet", until the flaws showed up.

"Go Tricky": travel faster than light. Then the causality problem rises up and bites you on the fundament.
