Looking closer t2.micro has following congiguration:
1 GB RAM
So basically it is as I was running my stuff on
less than a Rasberry Pi (4 cores, 2GB RAM). Ouch!
To surpass my MacBook Pro (4 cores 16GB RAM)
I would have to run it on t2.2xlarge with:
32 GB RAM
Which is $0.376 per hour, or $279 per month.
The AWS is a good option for short sessions when very powerful computer instances are needed,
and it is good for corporate web servers,
but for normal researcher who needs to run experiments day in and day out I would recommend
to buy gaming machine with top GPU, or two.
