There were no jokes, a comment said that "let's plan our energy generation assuming it doesn't materialize, we can always recalibrate if it does".

I hope you will allow people still being sceptical and cautious about counting on fusion for at least another 20-30 years.

The progress that the physicists and engineers made is tremendous and I appreciate everyone's sacrifices to make fusion a viable energy source.

However, it isn't one yet and likely it won't be for decades. There are still plenty of engineering challenges, and once those are solved, comes the economical, bureaucratical challenges (just take a look at how bad most countries are in building new fission reactors).

Both can be true at the same time.

I don't know about you, but I am planning my life with the assumption that the energy I use won't be coming from fusion for the rest of it (and I am around 30).



There's little downside in taking the pessimistic side of a bet with an enormous payout on the optimism side.

I'm on the optimism side of that coin though.

It's by no means necessary for a joke to have been made in the comment I was replying to, for me to refer to it. The cliché is well known.
