What I'm REALLY looking forward to is the PersonalPowerPack(tm)s that
contain between a microgram and a gram of anti-matter and are good for 1kW
to 100 KW of continuous output, depending on model. Available energy is
about 1E14 Joule/gram (! :-) )

Cost breaks even with chemical energy at about $10 billion per gram.

The 1 microgram / 1 kW model will run 24/7 for about 12 years. Handy pocket
warmer.

The 1 gram / 100 kW model will maintain a manned craft in powered flight
24/7 for about forever.
